  1. Motion Object Segmentation, Recognition and Tracking Huiqiong Chen; Yun Zhang; Derek Rivait Faculty of Computer Science Dalhousie University

  2. 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

  3. GET-based Motion Segmentation:System Architecture

  4. System Data Flow

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

  6. Original frame GET Map MGET groups Segmentation result Sample 2: Express Way Sequence

  7. License Recognition and Tracking • 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.
