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

Abstract

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.

The Same GPS-Induing-Time and Its Application in the Synchronized On or Off Navigation Mark Light

“…However, there will always be a slight variation in clock rates from satellite to satellite. Close monitoring of the clock of each satellite from the ground permits the control station to insert a message in the signal of each satellite which precisely describes the drift rate of that satellite's clock [2][3][4]. The insertion of the drift rate effectively synchronizes all of the GPS satellite clocks.…”
