Reasarch of Motion Estimation Algorithm in Video Compression
Chang Shu-juan · Modern Electronics Technique · 2010
MVFAST video compression algorithm is an important motion estimation algorithm,but it lacks the consideration of time domain correlation of images.This will result in an inappropriate division of motion types.Therefore,an improved adaptive motion estimation algorithm for motion vector field is presented to solve the problem.The new algorithm based on classifiable search mode in MVFAST improves the classification of motion intensity,imports the relative motion intensity classification of fast moving block to adaptively choose search strategy,uses more simple search method,and finishes the search adaptively.The result of experiments proves that the improved algorithm can improve the search velocity obviously in comparison with MVFAST algorithm.
