The Tactics Analysis about Early Phase Ends of the Partial Distortion Search

The article analyzes the advantage and disadvantage of part lacking fidelity searching algorithm, based on early ending technology thought. Given the disadvantage of the partial distortion search (PDS) algorithm, it brings up one kind of improved method which is similar to it. The improved algorithm also calculates sum of absolute difference (SAD) once within a row and add it to the block pixel SAD, but the two disadvantages of part lacking fidelity searching algorithm has been improved. The results of related experiment show that the early termination of fine granularity adaptive threshold and search points in the levels of early termination of the introduction of adaptive strategies used in the paper improves the speed moving estimation. This will promote the transmission quality of network video frequency to a new higher grade.
