Abstract: There has been a growing interest in compressive sensing and sparse representation in the past few years. In this talk, Professor Yang will present some recent newest results on how these theories can be extended and applied for constructing effective appearance models within the context of online object tracking.

First, Prof. Yang will present the recent results on compressive tracking. The proposed appearance model employs non-adaptive random projections which preserve the structure of image feature space. A sparse measurement matrix is adopted to efficiently compress the features in a low-dimensional space for foreground and background separation, thereby facilitating real-time object tracking.

Second, Prof. Yang will present a collaborative model for object tracking in which they exploit both holistic templates and local representations. They develop a sparsity-based discriminative classifier and a sparsity-based generative model. Within their tracking scheme, the collaboration of generative models and discriminative classifiers contributes to achieve more robust results.

Finally, while much progress has been made in recent years with efforts to share code and data sets, it is of great importance to develop a library and benchmark to gauge the state of the art. He will present some of their findings on large scale experiments with different evaluation criteria to understand how these algorithms perform. These findings also reveal critical components for a robust tracker for future research.
