Block Matching Early Termination Method Based on Sensor Electronic Image Stabilization

LI Bing;ZHANG Chao;College of Information Technology, Hebei Normal University;Modernization Teaching Center, Hebei University of Environmental Engineering;  
A novel block matching early termination method, based on sensor electronic image stabilization, was proposed to improve operation speed and stabilization precision. It used a gyro to detect the motion situation of camera system and estimated the motion direction. According to the information captured by gyro, the early termination method could find out the singular points of local motion estimation, and then break the operation and got rid of the singular points. The method could reject the singular points without acquiring all local motion vector information, so it reduced the operation and increases calculation speed. Moreover, the image stabilization precision was improved by better consistency of local motion vector set. The experiment result indicates that the operation speed is increased 79.50 percent, the precision is improved 13.04 percent.
