Abstract:

The multipatternsbased nonsymmetry antipacking pattern representation model is a nondestructive image expression method. This paper focuses on the typical model of points, straight lines, rectangles and triangles and presents an image representation method based on multipatterns. And the typical triangular pattern includes four directionel nonrightangled isosceles triangles. In this paper, we induce the basic idea of MNAM,analyse the structure of data storage,and give the encoding and decoding algorithms and the algorithm complexity. The results show that the image which uses MNAM has very good performance in the compression ratio and the reconstruction image quality.

Key words: multipatterns;nonsymmetry antipacking pattern representation model;image compression
