Real-Time Stabilization Aboat Image with Big Target Based on SAD Algorithm

The scenes of video sequence are very complex, different measures must be taken to solve the jitter of video sequence. Refer to the scene of big target and small background, block matching based on sum of absolute differences (SAD) algorithm is chosen after the comparison of different methods because of its good matching result and less computation. Then full search (FS) method is used to find the optimal matching point, and the high accuracy offset of two frames is calculated. By means of motion compensation according to the offset of current frame relative to reference frame, a reunited video sequence after image stabilization is accomplished.
