Extended difference function and its application in image motion estimation;

A fast motion estimation search algorithm based on vector prediction;

Optimization of multi-mode motion estimation algorithm in H.264;

The focus are images variable bit rate coding,movement estimation,loss priority assignment,cell construction,lost cell compensation.

The movement estimation is an important part of the video compression, it removes the time redundancy between the picture sequence thus to compression the video pictures, therefore, the movement estimation is the most consuming one of video compression.

With the application of the kinematical features to the layer image processing of translation objects, translation military target recognition and movement estimation could be obtained in natural environment.

Review and prospect of 3-D motion estimate based on image sequences;

In this paper ,a technique of Kalman filter based on 4×4- block algorithm is proposed to improve the motion estimates and enhance the motion compensation.

The requirement of the running time and accuracy of the motion estimate searching algorithm for the mobile video communication is proposed.

This paper presents an adaptive fast motion-estimation algorithm based on H.

In order to eliminate the artifacts such as edge blur and image "ghosting"(motion blur) when applying the existing pre-processing algorithm to video sequences,an adaptive pre-processing algorithm based on motion-estimation is proposed for noise reduction and bit-rate decrease.

An improved post-processing technique is developed to remove MRI artifact arising from rigid translation motion: First,the spectrum shift method is applied to remove phase-encoded direction translation motion.

The algorithm needs the manipulator to execute two translation motions and a rotation motion,and requires only two feature points in the scene.
