Video motion detection based on blocking and frame difference;

With the frame difference,the moving target is identified;with open and close operation in the morphologic,the two-value image is filtered;with tracking and label to the moving area,the target is surrounded with a rectangle.

A new method based on adaptive background subtraction and frame difference for the real-time detection .

First the image difference method and color analysis technique based on the HSI color model are applied to extract the fire-like moving region between two consecutive fra-mes.

A new approach was put forward,for instantaneous cycle-slip detecting suitable for reference baseline in GPS network RTK in which according to the known coordinates of reference stations,the float ambiguities were solved to detect circle-slips and then the search range of circle-slips were confirmed,at last the circle-slips were solved combining with the geometry-free phase combination.

In conventional motion compensated temporal filtering based wavelet coding scheme,where the size of group of picture and low-pass frames positions are fixed,and the motion activities in video sequences are not considered.

Studying UWB technology, especially UWB base-band data processing, including framing and modulation, is of great significance.

In this paper the basic architecture of DVB-S2 framing is researched, the implementation of the architecture is put forward, related simulation model is established, and the implementation of the architecture is validated by computer simulation based on SPW (Signal Progressing Worksystem).
