Block Matching Algorithm based on RANSAC Algorithm
A new type of real-time image stabilization system is introduced in present paper. RANSAC Algorithm is used in the system. The accuracy and speed of image stabilization is improved effectively. A low-cost and high-performance solution of real-time digital image stabilization system is given in this paper. Video stabilization working principle is discussed and the moving image mathematical model is set up. The RANSAC Algorithm can reduce the amount of calculation and the error rate of block matching. Simulation of the real-time image stabilization system is accomplished. The result shows the new model is effective; the power SNR of the video is raised about 8–10dB.
