把彩色图象处理成由图案组成的二色图象

Process the Color Image into Binary Image Made up of Pattern

根据抖动原理，巧妙定义抖动矩阵，把彩色图象灰度化，结合特定图案的抖动矩阵对灰度图象进行二值化处理，最后使彩色图象变成了一幅有特殊图案组成的二色图象，并解决了抖动过程中的一些特殊问题。

Base on the theory of dithering, define a dithering matrix, and make color image gray. According the dithering matrix, processed the gray image into binary image made up of a lot of pattern and solved some problems among it.
