Abstract

In Computer Vision, video segmentation is a challenging problem because it involves a large amount of data and object appearance may significantly change over time. In this talk, I will mainly introduce probabilistic models for video segmentation problem. Specifically, I will talk about a bottom-up approach for the combination of object segmentation and motion segmentation using a novel graphical model, which is formulated as inference in a conditional random field model. This model combines object labeling and trajectory clustering in a unified probabilistic framework. In the end of the talk, I will highlight some promising research directions in this area.
