A new concept of the window s vertex encoding is proposed for the first time based on the essential characteristic of the line clipping against polygonal window.

Analysis of Form Image Based on Vertex Chain Code;

This paper presents a new filling algorithm for vertex chain code.

Research on effect of vertex encoding method to maximum clique algorithm;

This paper introduces the algorithm of the transformations among vertex chain code(abbreviation of VCC), Freeman chain code and boundary chain code for 8-site neighborhood digital images.

A new method to trace region contours and generate chain code tree was proposed by defining the vertex chain code and constructing the pixel vertex matrix of binary images.

A point matching method with coded points and epipolar constrain is des cribed.

By employing the matching technology based on combining coded points and non-coded point,we discuss the method of sub pixel reference point center location and identification of two kinds of targets point.

The high accuracy center measuring method of marked points technique based on the fitting sub-pixel edge, and the methods of coded points designing and coded points auto-detecting were investigated.

Optimization of nonline simulated moving bed chromatography with real coded genetic algorithms;

An effective strategy based on real coded genetic algorithms was developed to optimize the operating conditions of simulated moving bed chromatography.
