3-D Face Analysis and Identification Based on Statistical Shape Modelling

This paper presents an effective method of statistical shape representation for automatic face analysis and identification in 3-D. The method combines statistical shape modelling techniques and the non-rigid deformation matching scheme. This work is distinguished by three key contributions. The first is the introduction of a new 3-D shape registration method using hierarchical landmark detection and multilevel B-spline warping technique, which allows accurate dense correspondence search for statistical model construction. The second is the shape representation approach, based on Laplacian Eigenmap, which provides a nonlinear submanifold that links underlying structure of facial data. The third contribution is a hybrid method for matching the statistical model and test dataset which controls the levels of the model’s deformation at different matching stages and so increases chance of the successful matching. The proposed method is tested on the public database, BU-3DFE. Results indicate that it can achieve extremely high verification rates in a series of tests, thus providing real-world practicality

Management of chemical and biological risks in agri-food chain

Paper presents diverse modes of governance of chemical and biological risks in agri-food sector, assesses their efficiency, complementarities, and challenges, and suggests recommendations for public policies improvement. It defines governance as system of social order responsible for particular behavior of agents; specify various (institutions, market, private, public) mechanisms of risk governance and (natural, technological, behavioral etc.) factors of efficiency; and suggest a framework for analysis and improvement of risk governance. New opportunities for risks governance relate to: modernization of technologies and institutional environment; specialization, concentration, and integration; “willingness to pay” and consumers and media involvement; national and transnational cooperation. Risk management challenges are associated with: new threats and risks; separation of risk-creation from risk-taking; vulnerability of mass production, distribution and consumption; high adaptation and compliance costs; unequal norms, implementing capability, policies and private strategies; public failures; and informal sector. Policies improvement is to incorporate governance issues taking into account type of threats and risks, specific factors, and comparative benefits and cost (including third-party, transacting, time); employ more hybrid modes introducing and enforcing new rights, and supporting private and collective initiatives; give greater support to multidisciplinary and interdisciplinary research on factors, modes, and impacts of risk-governance.risk management; market, private, public governance; agri-food chain
