Multiple Objects Tracking via Topology Adaptive Active Membrane

Tracking multiple deformable objects simultaneously in a video is a challenging problem. The tracking is more difficult when the objects are touching each other while they are moving or suddenly appear in or disappear from a frame of the video. In this paper we propose a parametric active membrane, which can change its topology to detect and track multiple objects present in the video. The membrane evolves in image space and also along the image intensity surface and if requires, splits into multiple membranes to track multiple objects. The methodology is tested on real video segments that demonstrates the efficacy of the proposed scheme.
