Aims Goal of this research To achieve a robust, low-complexity and accurate method for motion segmentation by using perceptual organization principles Motivation The role of Perceptual organization in vision is critical to success. Proposed method: GET based motion segmentation Applications Video coding and compression Video surveillance Military target detection Medical Imaging Traffic Monitoring

GET-based Motion S egmentation: System Architecture

Sample 1: Walk Man Sequence Original frame GET Map MGET groups Segmentation result

Sample 2: Express Way Sequence Original frame GET Map MGET groupsSegmentation result

Goal develop a practical solution to extract license plate of moving vehicles so that the license plate of each vehicle passing by can be identified automatically. Key idea combine motion tracking with region detection use application specific knowledge to guide for the target region detection: region shape, ratio of width to height use knowledge previously discovered to generate a Region of Interest which focuses tracking to relevant areas.
