Object Tracking in Real Time Video Sequences Using a Fast Level Set Method

We propose a method for determining the shape (2D outline of the object) and follow-up position (set of simple geometric transformations on position), using a level set based curve evolution and combining the benefits of using the pixel-wise posterior term with a fast level-set algorithm to approximate curve evolution. The pixelwise posterior allows us to marginalize the model parameters at pixel level, and the fast level-set algorithm avoids the need of solving partial differential equations (PDEs). Our proposed implementation can accurately process a higher number of frames per second, bringing real-time performance on standard hardware systems.
