中文摘要：

针对多子模式非对称逆布局模式表示模型,引入灰度插值的方法,对原有的点、直线、矩形和三角形四种模式重新进行了定义,一个三角形插值块可以通过三个顶点的位置和灰度值按照线性插值的方法生成块内任意一点的灰度值.理论分析和实验结果表明在引入插值方法以后,与MNAM方法相比,算法的复杂度会增加,图像的压缩比可能略有降低,但是图像的重建质量则会得到明显的提高.

英文摘要：

This paper inducts gray interpolation method to MNAM,redefines the four kinds of pattern,i.e.dot,line,rectangle and triangle.Based on the locations and gray value of three points,linear interpolation method can calculate the gray value of any point in the area.The theoretical analysis and the experimental results show that the algorithm complexity is increased,image compression ratio decreased slightly,but the quality of image reconstruction has a marked improvement after introducing the interpolation method.
