图象处理中的抖动模式问题是彩色图象打印输出的一个关键问题.提出由评价函数驱动的模式抖动方式,并利用模拟退火算法加以实现,在此基础上,提出了几种影响抖动模式的评价函数.实验结果表明该方法优于Jarvis抖动处理.

[Abstract]
The dither pattern in image processing is studied in this paper and it is crucial in color image printing output. First, one pattern dithering method based on the evaluating function is presented and it is implemented by applying simulated annealing algorithm. Then some improved evaluating functions are presented. The results show that this method is better than Jarvis Dithering.
