Abstract
A process to isolate objects of interest in an image uses a model which takes into account the artifacts stemming from the JPEG compression. The pixels are sorted accordingly to layers which regroup pixels of similar value, and the background is modeled by a polygon from an additional picture. Segmentation based on the knowledge of the background and the layers is then performed. This method provides good results for segmentation, while being sufficiently fast to be implemented for real time application.
