d -Change software - motion detection

Participants : Fabien Spindler (Lagadic team), Patrick Bouthemy.

d -change is a multi-platform object-oriented software to detect mobile objects in an image sequence acquired by a static camera. It includes two versions : the first one relies on Markov models and supplies a pixel-based binary labeling, the other one introduces rectangular models enclosing the mobile regions to be detected. It simultaneously exploits temporal differences between two successive images of the sequence and differences between the current image and a reference image of the scene without any mobile objects (this reference image is updated on line). The algorithm provides the masks of the mobile objects (mobile object areas or enclosing rectangles according to the considered version) as well as region labels enabling to follow each region over the sequence.
