Abstract

Purpose

This paper aims to develop the Hybrid feature descriptor and probabilistic neuro-fuzzy system for attaining the high accuracy in face recognition system. In recent days, facial recognition (FR) systems play a vital part in several applications such as surveillance, access control and image understanding. Accordingly, various face recognition methods have been developed in the literature, but the applicability of these algorithms is restricted because of unsatisfied accuracy. So, the improvement of face recognition is significantly important for the current trend.

Design/methodology/approach

This paper proposes a face recognition system through feature extraction and classification. The proposed model extracts the local and the global feature of the image. The local features of the image are extracted using the kernel based scale invariant feature transform (K-SIFT) model and the global features are extracted using the proposed m-Co-HOG model. (Co-HOG: co-occurrence histograms of oriented gradients) The proposed m-Co-HOG model has the properties of the Co-HOG algorithm. The feature vector database contains combined local and the global feature vectors derived using the K-SIFT model and the proposed m-Co-HOG algorithm. This paper proposes a probabilistic neuro-fuzzy classifier system for the finding the identity of the person from the extracted feature vector database.

Findings

The face images required for the simulation of the proposed work are taken from the CVL database. The simulation considers a total of 114 persons form the CVL database. From the results, it is evident that the proposed model has outperformed the existing models with an improved accuracy of 0.98. The false acceptance rate (FAR) and false rejection rate (FRR) values of the proposed model have a low value of 0.01.

Originality/value

This paper proposes a face recognition system with proposed m-Co-HOG vector and the hybrid neuro-fuzzy classifier. Feature extraction was based on the proposed m-Co-HOG vector for extracting the global features and the existing K-SIFT model for extracting the local features from the face images. The proposed m-Co-HOG vector utilizes the existing Co-HOG model for feature extraction, along with a new color gradient decomposition method. The major advantage of the proposed m-Co-HOG vector is that it utilizes the color features of the image along with other features during the histogram operation.

Abstract

Purpose

In order to provide a general context for library implementations of open source software (OSS), the purpose of this paper is to discuss the existing presence of OSS in libraries, the functionality and variety of OSS products, and the need for further study into the application of OSS technologies in libraries.

Design/methodology/approach

The paper is based on a literature review.

Findings

This paper endeavors to provide a broad overview of the deepening relationship between libraries and OSS. Libraries are seeking alternatives to proprietary applications which may require specialized support and/or services. Moreover, OSS and proprietary products have a functional verisimilitude, and, as proprietary applications developers anticipate user needs, so too do OSS contributors.

Practical implications

The degree of variance between proprietary and OSS applications, features, support, and compatibility is continually lessening, so libraries are increasingly making use of less costly alternatives to subscription based tools.

Originality/value

The use of OSS in libraries is an increasing trend. OSS tools and implementations provide library institutions with access to a dynamic and cost effective solution for servicing user groups, manipulating large volumes of content, and facilitating communications between various institutional and public entities. This paper gives an holistic perspective albeit in a short form.

Abstract

Purpose

The purpose of the present study is to explore the possibility of introducing a 3D environment in the library by reviewing current literature and to provide a good understanding of different purposes of using this immersive environment.

Design/methodology/approach

The present paper is a narrative account of libraries’ presence in the virtual world in combination with an overview of how libraries respond to the 3D environment. Relevant data for the review paper have been collected from library websites, books, journal articles, interview, etc.

Findings

The study found purposive involvement of libraries in this immersive environment which indicates that users use this exciting 3D medium to satisfy their information requirement.

Research limitations/implications

The paper basically considers publications containing observations of broader research community in the relevant field and contents in websites dealing with virtual world and outlines the major features as discussed in available documents. The review study infers that the implementation of 3D project in libraries requires a mindset for the specific approach, from the end of both librarians and users, together with involvement of funds. Therefore, a library may start with a beta project and observe the effectiveness from the users’ perspective before embarking on a full-fledged project.

Originality/value

With numerous examples, as evident from publications and websites, the current review study makes an attempt to improve the understanding of librarians towards informed selection of projected purposes to be integrated with the virtual world from library perspective. The study also presents different approaches of libraries motivating users in the virtual world that other libraries may follow while considering their 3D library project.

Abstract

Purpose

What this paper aims to tackle is how much did the return of rural migrant labor during the financial crisis affect China's GDP and the growth rate of the national economy.

Design/methodology/approach

This paper constructs a computable general equilibrium (CGE) model and uses data of China's 2007 Input-Output Table to analyze the impact of the return of rural migrant labor on China's economy during the financial crisis.

Findings

The results show that the return of rural migrant labor during the financial crisis had substantial impacts on China's economy. The national GDP decreased by about 0.499-1.463 percent, mainly due to the number of rural labor who migrated from the non-agricultural sector to agriculture. Of the major sectors of economy, the manufacturing, construction and other services sectors were the most affected.

Originality/value

This paper assesses the impacts of return of rural migrant labor during the financial crisis on China's GDP and the growth rate of the national economy.

Abstract

Summarizes the UK′s food chemical surveillance programme. This programme is an extensive series of checks, tests and analyses (approximately 130,000 per annum) designed to monitor the safety and quality of the UK′s food supply. The paper describes the scale of the programme and its management through the Steering Group on Chemical Aspects of Food Surveillance (SGCAFS) and its 11 working parties‐which cover the wide range of food surveillance activities including chemical contaminants, natural toxicants, nutrition, food additives, radionuclides and authenticity. Although the programme′s results are generally reassuring, important information is produced on emerging potential problems. Provides examples where this surveillance has enabled these potential problems to be identified and appropriate remedial action taken. Describes the extensive publication of surveillance data through the Food Surveillance Paper series (HMSO) and reports on the recent Ministerial decision for the rapid publication of the most important food surveillance data.

Abstract

Purpose

The purpose of this paper is to explore how different forms of integration interact with environmental dynamism to influence the outcomes of a buyer–supplier relationship (BSR). Specifically, the authors assess the impact of communication, operational process integration (OPI) and joint knowledge exploration (JKE) on the economic value and competitive differentiation generated by the BSR. Furthermore, the authors assess the moderating role of environmental dynamism in changing the performance implications of these different forms of integration.

Design/methodology/approach

The authors empirically test the theoretical model using survey data collected from North America. The authors apply techniques such as confirmatory factor analysis, regression and a variety of robustness checks to ensure the validity of the findings.

Findings

The results indicate that OPI and JKE are useful in generating higher value from key supply chain relationships. However, communication does not directly influence performance outcomes, rather it assists in the implementation of other forms of integration. In stable environments, better returns can be obtained from focusing on OPI, while in dynamic environments JKE becomes far more important.

Originality/value

This study shows that different aspects of integration have very different performance implications and that selective integration can outperform broad-based integration in some conditions. More importantly, the performance implications depend on environmental dynamism in unique ways, where greater integration is not always the best response to dynamic business conditions. The results allow managers to make better decisions regarding what forms of integration to establish in key supply chain relationships.
