Abstract

We propose a novel method for tracking objects in a video scene that undergo drastic changes in their appearance. These changes may arise due to out-of-plane rotation, abrupt or gradual changes in illumination in outdoor scenarios, or changing position with respect to near light-sources indoors. The key problem with most existing models is that they are either non-adaptive (rendering them non-robust to object appearance change) or use a single tracker output to heuristically update the appearance model at each iteration
(rendering them vulnerable to drift). In this paper, we take a step toward general
real-world tracking, in a principled manner, proposing a unified generative model for Bayesian multi-feature, adaptive target tracking. We show the performance of our method on a wide variety of video data, with a focus on surveillance scenarios.
