基于阴影法和对角优先的RNAM图像表示
RNAM image representation based on shading approach and diagonal-first search
摘要
Abstract
Diagonal-first strategy for searching a rectangle subpattern was studied.By using the extended Gouraud shading approach and the diagonal-first search strategy,a rectangular non-symmetry and anti-packing pattern representation model（RNAM） image representation method was proposed,which was called diagonal-first RNAM coding（DRNAMC） method.By taking some idiomatic standard gray images in the field of image processing as typical test objects,and by comparing the proposed DRNAMC method with the popular S-tree coding（STC） method,the experimental results show that the former has the higher compression ratio and the less number of blocks than the latter whereas maintaining the image quality,and therefore it is a better method to represent the gray image.关键词
