Assuming the backward frame(reference frame) was encoded by the variable size block matching backward motion estimation and compensation,then the current frame was encoded by the bi-directional motion estimation and compensation.

The variable-size block motion compensation based on pre-knowledge is incorporated into bilateral motion estimation and the adapted multi-stage motion vector processing and adaptive motion compensated interpolation are adopted so as to resolve the problems of overlapping,hole and block artifacts .

Incorporated the variable-size block motion compensation based on pre-knowledge thresholding into bilateral motion estimation,and adopted the adapted multi-stage motion vector processing so as to avoid the cumulation of motion estimation error.

Output probability of speech/non-speech state is calculated sequentially using a Gaussian mixture model,backward estimation and parallel non-linear Kalman filter are used to estimate non-stationary noise.

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.
