A series of key problems about the binary image profiled processing, including mainly the parallel pre processing, the chain code tracing, the directional chain code recording and the smoothing process are discussed.

In this paper, we describe parallel processing technology ── Pipelined oper- ation, folding parallel technology and parallel preprocessing, and actual examples of its ap- plication.

Seismic parallel processing application framework based on design pattern.;

Influence of communication between nodes on the speed-up ratio in parallel processing;

Reliability evaluation of composite generation and transmission system using Monte-Carlo simulation and parallel processing;

Application research of concurrent computing and concurrent processing technique

The real-time multi-task concurrent processing in DOS environment is described.

The system is realized by the method of concurrent processing,real time interrupt and multi process.

New program parallel processing method based on Petri net;

Multiprocessor parallel process technique in precision guidance;

Parallel process of digital radar signal is an important field,and parallel process structure is the base to process digital radar signal.

Made the complex symmetrical matrix become to symmetrical diagonally matrix through the Householder transform and divide up the matrix for parallel computing base on the divide-and-conquer idea,which avoids redundant operation and reduces the hardware capability limits in practice,what provide a better background for subspace direction finding and others application.
