Face recognition has been widely investigated in the last decade. However, real world application for face recognition is still a challenge. Most of these face recognition algorithms are under controlled settings, such as limited viewpoint and illumination changes. In this paper, we focus on face recognition which tolerates large viewpoint change. A novel framework named Lucas-Kanade Scale Inva...

Owe to the rapid development of deep neural network (DNN) techniques and the emergence of large scale face databases, face recognition has achieved a great success in recent years. During the training process of DNN, the face features and classification vectors to be learned will interact with each other, while the distribution of face features will largely affect the convergence status of netw...

Are categorization and visual processing independent, with categorization operating late, on an already perceived input, or are they intertwined, with the act of categorization flexibly changing (i.e. cognitively penetrating) the early perception of the stimulus? We examined this issue in three experiments by applying different categorization tasks (gender, expressive or not, which expression a...

Community based interventions increase knowledge scores and also have an impact of sexual behaviours with regard to HIV. However the problem remains as to how best to scale up these interventions and how best to overcome real or perceived barriers to their uptake. Community based interventions have multiple components and some will be more difficult to widen out than others. Those that involve ...

The ability to recognize an unfamiliar individual on the basis of prior exposure to a photograph is notoriously poor and prone to errors, but recognition accuracy is improved when multiple photographs are available. In applied situations, when only limited real images are available (e.g., from a mugshot or CCTV image), the generation of new images might provide a technological prosthesis for ot...

conclusions this study estimated that the prevalence of major depression among iranian individuals with pd living in kermanshah as 44%. major determinants of depression were female gender, rigidity, impaired posture, masked face, hyposmia, and anhedonia. results a total of 350 patients (52.9% men and 47.1% women) participated in this investigation. female gender (36.5% in women vs. 13.0% in men...
