Besides,carried out adaptive motion vector refinement with dual-threshold to reduce redundant computation if the reconstructed motion vector was already optimal.

Taking three sections of this curve were joined for example, this paper inquired into the construction of the revised iso-velocity motion curve.

This paper illustrated processing methods for complex surface seismic data with low signal to noise ratio seismic data from Hefei Basin and proposed a process which consised of statics, noise suppression, high precision velocity analysis, and revision of NMO.

Reconstruction has been made on an eccentric plier which is the only such machine of Russian made in the 1950s still remaining in China by computer control of which the model for speed tracker algorithm and dynamic correction is presented in the paper.

the aim-ing error in practical launching missiles, and thinking over the dynamic correction of thetarget s maneuvering movement in the course of guidance, the important conclusion aboutguiding the correct designing and using proportional guid.

The main causes of the dynamic error occurred in the weighing process are analysed,and an improved method based on dynamic correction and second-order prediction is proposed to reduce the influence on the data of preact.
