报告题目：Graph decomposition for multi-person tracking, pose estimation and motion segmentation

主持人：张姗姗（德国马普所）

报告摘要：

Understanding people in images and videos is a problem studied intensively in computer vision. While continuous progress has been made, occlusions, cluttered background, complex poses and large variety of appearance remain challenging, especially for crowded scenes. 

In this talk, I will explore the algorithms and tools that enable computer to interpret people's position, motion and articulated poses in the real-world challenging images and videos. More specifically, I will discuss an optimization problem whose feasible solutions define a decomposition of a given graph.  I will highlight the applications of this problem in computer vision, which range from multi-person tracking [1,2,3] to motion segmentation [4].  I will also cover an extended optimization problem whose feasible solutions define a decomposition of a given graph and a labeling of its nodes with the application on multi-person pose estimation [5].
