Abstract

Purpose

The growth of police operated surveillance cameras has out-paced the ability of humans to monitor them effectively. Computer vision is a possible solution. An ongoing research project on the application of computer vision within a municipal police department is described. The paper aims to discuss these issues.

Design/methodology/approach

Following the demystification of computer vision technology, its potential for police agencies is developed within a focus on computer vision as a solution for two common surveillance camera tasks (live monitoring of multiple surveillance cameras and summarizing archived video files). Three unaddressed research questions (can specialized computer vision applications for law enforcement be developed at this time, how will computer vision be utilized within existing public safety camera monitoring rooms, and what are the system-wide impacts of a computer vision capability on local criminal justice systems) are considered.

Findings

Despite computer vision becoming accessible to law enforcement agencies the impact of computer vision has not been discussed or adequately researched. There is little knowledge of computer vision or its potential in the field.

Originality/value

This paper introduces and discusses computer vision from a law enforcement perspective and will be valuable to police personnel tasked with monitoring large camera networks and considering computer vision as a system upgrade.

Abstract

Purpose

This study aims to examine the imagining of libraries and the depiction of library services in contemporary science fiction novels. Analyses of libraries in contemporary science fiction may reveal expectations of libraries and the roles they play in future societies. These may, in turn, be used by the library profession to innovate and to discover opportunities to design and improve library services that meet the expectations of library users now and in the future.

Design/methodology/approach

This research applied a content analysis approach to examine references to libraries in a purposeful sample of science fiction novels published between 2009 and 2019. The sample consists of 29 novels selected from the 2010–2020 winners of the Hugo Award for Best Novel, The Nebula Award for Best Novel, the Locus Award for Best Science Fiction Novel, The Philip K Dick Award and the Arthur C Clarke Award.

Findings

This research finds that libraries are a common feature within contemporary science fiction novels, primarily as part of the background setting of the narratives. Libraries are particularly common in peri-apocalyptic novels, often as “reinvented” libraries. This research identifies considerable differences in the way libraries and information access and use are depicted and documented in science fiction worlds of plenty, compared to those of scarcity. Other key themes discussed include freedom of access to information, and the supposedly common negative stereotyping of libraries.

Originality/value

Existing literature indicates anxiety about the future of libraries which the findings of this research do not support. The insights gained suggested instead, the emergence of an image of libraries as being embedded in the fabric of societies. This indicates the expectation of the place and role of libraries in contemporary societies. Libraries and their services must be adeptly placed and woven into the many facets of the societies they serve.

Abstract

Purpose

Social signal processing under affective computing aims at recognizing and extracting useful human social interaction patterns. Fight is a common social interaction in real life. A fight detection system finds wide applications. This paper aims to detect fights in a natural and low-cost manner.

Design/methodology/approach

Research works on fight detection are often based on visual features, demanding substantive computation and good video quality. In this paper, the authors propose an approach to detect fight events through motion analysis. Most existing works evaluated their algorithms on public data sets manifesting simulated fights, where the fights are acted out by actors. To evaluate real fights, the authors collected videos involving real fights to form a data set. Based on the two types of data sets, the authors evaluated the performance of their motion signal analysis algorithm, which was then compared with the state-of-the-art approach based on MoSIFT descriptors with Bag-of-Words mechanism, and basic motion signal analysis with Bag-of-Words.

Findings

The experimental results indicate that the proposed approach accurately detects fights in real scenarios and performs better than the MoSIFT approach.

Originality/value

By collecting and annotating real surveillance videos containing real fight events and augmenting with well-known data sets, the authors proposed, implemented and evaluated a low computation approach, comparing it with the state-of-the-art approach. The authors uncovered some fundamental differences between real and simulated fights and initiated a new study in discriminating real against simulated fight events, with very good performance.

Abstract

Public video surveillance tends to be discussed in either utopian or dystopian terms: proponents maintain that camera surveillance is the perfect tool in the fight against crime, while critics argue that the use of security cameras is central to the development of a panoptic, Orwellian surveillance society. This paper provides an alternative, more nuanced view. On the basis of an empirical case study, the paper explores how camera surveillance applications do not simply augment surveillance capacities, but rather have to deal with considerable uncertainties in the process of producing a continuous, effective, all‐seeing gaze. The case study shows that the actions of human operators and the operation of camera technologies each place limits on the execution of electronic visual surveillance, instead of efficiently enhancing the powers of the surveilling gaze. The analysis suggests that the effects of video surveillance are rather ambivalent and uncertain, thus showing that public camera systems are not simply beneficial or malign.

Abstract

Purpose

This paper aims to address the problem of uncertain product quality in digital light processing (DLP) three-dimensional (3D) printing, a scheme is proposed to qualitatively estimate whether a layer is printed with the qualified quality or not cured .

Design/methodology/approach

A thermochromic pigment whose color fades at 45°C is prepared as the indicator and it is mixed with the resin. A visual surveillance framework is proposed to monitor the visual variation in a period of the entire curing process. The exposure region is divided into 30 × 30 sub-regions; gray-level variation curves (curing curves) in all sub-regions are classified as normal or abnormal and a corresponding printing control strategy is designed to improve the percentage of qualified printed objects.

Findings

The temperature variation caused by the releasing reaction heat on the exposure surface is consistent in different regions under the homogenized light intensity. The temperature in depth begins to rise at different times. The temperature in the regions near the light source rises earlier, and that far from the light source rises later. Thus, the color of resin mixed with the thermochromic pigment fades gradually over a period of the entire solidification process. The color variation in the regions with defects of bubbles, insufficient material filling, etc., is much different from that in the normal curing regions.

Originality/value

A temperature-sensitive organic chromatic chemical pigment is prepared to present the visual variation over a period of the entire curing process. A novel 3D printing scheme with visual surveillance is proposed to monitor the layer-wise curing quality and to timely stop the possible unqualified printing resulted from bubbles, insufficient material filling, etc.

Abstract

Purpose

The purpose of the paper is to explore the potential of visual cultural studies (VCS) to inform and extend research on “accounting and the visual”.

Design/methodology/approach

A VCS framework is utilized: to draw together and organize work on “accounting and the visual”; and to illustrate how concepts and empirical studies from VCS can develop and extend accounting research.

Findings

The “visual culture turn” in the social sciences has generated considerable theorizing and empirical research pertinent to accounting research. In particular, it can deepen studies of accounting visuality – accounting's visibilities, invisibilities and ways of seeing – and stimulate new imag(in)ings.

Practical implications

The paper introduces accounting researchers to questions, topics, concepts and debates in the VCS field and illustrates how accounting and VCS research can mutually inform each other and foster interpretive/critical accounting projects.

Originality/value

VCS can frame studies of “accounting and the visual” (i.e. affirm it as a distinct field, with rich interdisciplinary connections) with implications for developing and extending accounting research.

Abstract

Purpose

To discuss and review the shift to computer enhanced self‐monitoring CCTV surveillance systems of public spaces and the social implications of this shift.

Design/methodology/approach

A review of the research and evaluation literature concerning CCTV surveillance systems culling out the history of public space CCTV systems and the concerns associated with first and second generation CCTV surveillance.

Findings

The main difference between first and second generation surveillance is the change from a “dumb camera” that needs a human eye to evaluate its images to a computer‐linked camera system that evaluates its own video images. Second generation systems reduce the human factor in surveillance and address some of the basic concerns associated with first generation surveillance systems such as data swamping, boredom, voyeurism, and profiling. Their enhanced capabilities, though, raise new concerns, particularly the expansion of surveillance and its intrusiveness.

Research limitations/implications

Additional research is needed to assess CCTV surveillance on a set of social dynamics such as informal guardianship activities by citizens.

Practical implications

The adoption of computer‐enhanced CCTV surveillance systems should not be an automatic response to a public space security problem and their deployment should not be decided simply on the technology's availability or cost.

Originality/value

This paper provides a concise overview of the concerns associated with first generation CCTV surveillance and how the evolution of computer‐enhanced CCTV surveillance systems will alter and add to these concerns. For researchers it details research questions that need to be addressed. For practitioners and government officials considering the use of public space CCTV surveillance it provides a set of issues that should be considered prior to system adoption or deployment.

Abstract

Purpose

This paper presents a survey of research into interactive robotic systems for the purpose of identifying the state of the art capabilities as well as the extant gaps in this emerging field. Communication is multimodal. Multimodality is a representation of many modes chosen from rhetorical aspects for its communication potentials. The author seeks to define the available automation capabilities in communication using multimodalities that will support a proposed Interactive Robot System (IRS) as an AI mounted robotic platform to advance the speed and quality of military operational and tactical decision making.

Design/methodology/approach

This review will begin by presenting key developments in the robotic interaction field with the objective of identifying essential technological developments that set conditions for robotic platforms to function autonomously. After surveying the key aspects in Human Robot Interaction (HRI), Unmanned Autonomous System (UAS), visualization, Virtual Environment (VE) and prediction, the paper then proceeds to describe the gaps in the application areas that will require extension and integration to enable the prototyping of the IRS. A brief examination of other work in HRI-related fields concludes with a recapitulation of the IRS challenge that will set conditions for future success.

Findings

Using insights from a balanced cross section of sources from the government, academic, and commercial entities that contribute to HRI a multimodal IRS in military communication is introduced. Multimodal IRS (MIRS) in military communication has yet to be deployed.

Research limitations/implications

Multimodal robotic interface for the MIRS is an interdisciplinary endeavour. This is not realistic that one can comprehend all expert and related knowledge and skills to design and develop such multimodal interactive robotic interface. In this brief preliminary survey, the author has discussed extant AI, robotics, NLP, CV, VDM, and VE applications that is directly related to multimodal interaction. Each mode of this multimodal communication is an active research area. Multimodal human/military robot communication is the ultimate goal of this research.

Practical implications

A multimodal autonomous robot in military communication using speech, images, gestures, VST and VE has yet to be deployed. Autonomous multimodal communication is expected to open wider possibilities for all armed forces. Given the density of the land domain, the army is in a position to exploit the opportunities for human–machine teaming (HMT) exposure. Naval and air forces will adopt platform specific suites for specially selected operators to integrate with and leverage this emerging technology. The possession of a flexible communications means that readily adapts to virtual training will enhance planning and mission rehearsals tremendously.

Social implications

Interaction, perception, cognition and visualization based multimodal communication system is yet missing. Options to communicate, express and convey information in HMT setting with multiple options, suggestions and recommendations will certainly enhance military communication, strength, engagement, security, cognition, perception as well as the ability to act confidently for a successful mission.

Originality/value

The objective is to develop a multimodal autonomous interactive robot for military communications. This survey reports the state of the art, what exists and what is missing, what can be done and possibilities of extension that support the military in maintaining effective communication using multimodalities. There are some separate ongoing progresses, such as in machine-enabled speech, image recognition, tracking, visualizations for situational awareness, and virtual environments. At this time, there is no integrated approach for multimodal human robot interaction that proposes a flexible and agile communication. The report briefly introduces the research proposal about multimodal interactive robot in military communication.

Abstract

Purpose

This paper aims to examine the effects of transformations of the levels of visual and functional permeability and the types of uses on the ground floors of buildings on the perception of security and the occurrence of residential burglary, theft in residence, pedestrian mugging, vehicle robbery, vehicle theft and theft of items inside a vehicle on selected blocks.

Design/methodology/approach

Nine blocks divided into three groups were selected in Capão da Canoa, a Brazilian city that has been undergoing morphological transformations, including the replacement of buildings with residences and shops on the ground floor, with doors and windows facing the street, by buildings with a predominance of garage doors and blind walls on the ground floors. Data were collected through the application of questionnaires and interviews.

Findings

The results reveal, for example, that perception of greater security is related to the blocks with a greater number of functional and visual connections between the ground floor interfaces of the buildings and the open public spaces. In addition, the night period records the higher number of criminal occurrences, even on blocks with higher rates of visual and functional connections between the ground floor interfaces and the public open space and higher rates of residential and commercial uses on the ground floor of the buildings.

Originality/value

It is expected that the results of this paper will allow for greater knowledge and the revision of many urban guidelines regarding the effects of the transformations of ground floor interfaces from traditional to contemporary buildings in the perception of security and the occurrence of crimes in public open spaces and in neighbouring residential units. It is further evidenced the need to recognize the ground floor interface as an element of public interest, even if it belongs to a private property. Nonetheless, further research is needed on the relationships between the quantifications of the levels of visual and functional permeability, the different types of uses on the ground floor of buildings, movement of people and crimes in open spaces and buildings in different periods of the day.

Abstract

Purpose

The purpose of this paper is to explore the potential and adoption of closed-circuit television (CCTV) surveillance-based security system (hereafter “CCTV”) for enhancing the security of library materials in academic libraries of universities (central, state, deemed and private) and prestigious institutions such as Indian Institutes of Technology and Indian Institutes of Management in a developing country, i.e. India. The study also overviewed the CCTV policies of the studied libraries of universities/institutions as they relate to the ethical aspects of the surveillance system.

Design/methodology/approach

Structured questionnaire was designed and distributed among librarians of 24 academic libraries covering each zone of India in October 2019 in both physical and online manner. All 24 filled-in questionnaires were collected personally and online by the investigator were found valid eliciting a response rate of 100%. All the 24 filled-in questionnaires were included in the analysis of the interpretation of data. The response to 18 questions was analyzed in the form of tables and figures using descriptive statistical methods.

Findings

The study reveals that librarians’ found CCTV useful for security by controlling theft, unethical losses and missing items. It also helped to curb mutilation and vandalism, procurement of the rare material via the latest camera devices and night vision capturing, besides improving the service efficiency of the patron, as well as staff. The quantitative study surveyed security professionals to assess how each university/institution developed, deployed and integrated CCTV policies related to securing video data, safeguarding privacy and prevention of the potential for the unethical use of surveillance cameras. The analysis of the survey responses determined that more than 50% of the universities/institutions participating had a written CCTV policy. Further, library professionals find that the future of libraries lies in a CCTV system, so the cost should be brought down to improve return on investment by the mass adoption of this technology in a developing country such as India.

Research limitations/implications

The findings of the study showed that the potential uses of CCTV in Indian libraries are slow compared to that of the libraries of developed countries and some of the developing countries. Many of the CCTV policies that universities/institutions did have failed to include mandated training of personnel or provisions ensuring that their policies remained up-to-date. It is suggested that universities and institutions understudy should realize the benefits of CCTV systems and incorporate-related updated tools in the security and multi-purpose uses in the libraries to enhance the services for the users and security for the materials or collections.

Practical implications

The paper includes implications for libraries and their professionals to approach CCTV systems with ethical considerations for procurement of library collections, which help to detect mutilation/theft, observe the misbehavior of users, as well as staff and deployment, should not be decided merely while balancing security demands.

Social implications

The study is significant because it represents one of the earliest works to shed light on the current level of the use of CCTV system by librarians of studied libraries of universities/institutes in developing country such as India and how they are providing CCTV-based security and services, which are currently in its primitive nature. The study also suggested that select libraries are required to weigh up and balance many competing desires, demands and objectives.

Originality/value

This paper provides a concise overview of the various applications/area and uses of CCTV system including its procedures during implementation, merits and demerits while using the system described above in libraries and recommends this technology to other libraries for faster and better services for their users and security to their library materials in today’s technological advancement. It provides a set of issues that should be considered before system adoption or deployment.
