Any facial feature localization algorithm needs to incorporate two sources of information: 1) prior shape knowledge, and 2) image observations. Existing methods have primarily focused on different ways of representing and incorporating the image observations into the problem solution. Prior shape knowledge, on the other hand, has been mostly modeled using parametrized shape models. Parametrized shape...
This article presents the LIFEisGAME project, a serious game that will help children with ASDs to recognize and express emotions through facial expressions. The game design tackles the main experiential learning cycle of emotion recognition: watch and recognize, learn by doing, recognize and mimic, generalize or knowledge transfer to real life. We briefly describe the technology behind the character...
A pan-tilt-zoom (PTZ) camera, fixed in location, may perform only rotational movements. There is a class of feature-based self-calibration approaches that exploit the restrictions on the camera motion in order to obtain accurate point-correspondences between two configurations of a PTZ camera. Most of these approaches require extensive computation and yet do not guarantee a satisfactory result. In...
