An interpolation motion compensation method for video sequence

The video processing technology is becoming the indispensable bridge between the person and the information. Typically, a video processing pipeline consists of video signal demodulation, video decoding and video post processing. In order to adapt to the kinds of modern video formats, it is necessary that the additional frames are interpolated based on the original video sequence. The movement should be to accurately estimate so that the proper motion compensation of the frames can do in video. The importance is well considered between the operation speed and the accuracy of the algorithm. The paper introduces a bilinear interpolation algorithm, along the movement direction, that selects the proper pixels and normalizes. Taking advantage of the common video library, lots of experiments are carried out and compared to the common interpolation algorithm. It is verified that the proposed algorithm may improve the performance of motion compensation.
