This article deals with 3D-face model and 3D-pose extraction from a small set of couples of 2D-3D corresponding-points. Major drawbacks of current 3D model extraction solutions are either the computationally complexity or the oversimplified modeling. As it happens, applications like face tracking or augmented reality need a rapid, robust and… (More)
This article deals with facial segmentation and liptra-cking with feedback control for real-time animation of a synthetic 3D face model. Classical approaches consist in two successive steps : video analysis then synthesis. We want to build a global analysis/synthesis processing loop, where the image analysis needs the 3D synthesis and conversely. For that,… (More)
This article deals with facial segmentation and liptracking with feedback control by face model synthesis. On this topic, the search community is divided into two parts : analysis and synthesis. We want to use all the knowledge to create a global analysis/synthesis chain where the image analysis needs the 3D synthesis and conversely. As it happens,… (More)
For a videosurveillance application based on wireless transmission of images acquired with a static camera, we investigate two features within JPEG2000, namely the choice of a nonlinear color transform in order to improve color rendering at very high compression ratios, and the unsupervised extraction of regions of interest (ROI) by motion detection.
