| 摘 要： | 基于多子模式的非对称逆布局模式表示可以作为一种无损图像表示方法,本文以包括点、直线、矩形和三角形的典型多子模式为研究对象,提出了一种基于多种子模式的NAM图像表示方法.其中,三角形典型子模式包括四种走向的非等腰直角三角形,因此在子模式抽取时需要对三角形进行不等腰处理.本文给出了MNAM的表示思想,对其在计算机内的存储结...

| 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. |
