Quadrilateral zone producing algorithm for binary image

NIU Ji-ping,YU Zhi-chao(Dept.of Computer,Huanggang Normal University,Huangzhou 438000,Hubei,China)  
With the characteristics of zone of binary image,a quadtree quadrilateral zone producing algorithm is presented.The idea of this method is to use binary image to partition the zone into four areas with quadtree and,if the pixels in the same area have the same value then the area is presented as one element,otherwise,partition continually the area into smaller areas.The advantages of this method are as follows: At first,its binary shift can improve the efficiency of forming M_D code;secondly,the logarithm method is adopted to compress the pixel value of the area.This method combines the advantages of smaller memory consumption with higher running speed.
