| 摘 要： | 提出了一种对二值图像,尤其是打印图像的数据无损压缩方法。这种方法我们称作分散标准压缩(DRC),它的编码方案根据硬件压缩图像特性的不同而改变。模拟计算实验表明,分散标准压缩方法能够得到一种比当前国际标准的二值图像压缩比率还高30%的压缩比,这也说明该方法是切实有效的。

| Abstract: | This paper proposes a lossless data compression method for bi_level images, particularly printing images. In this method, which is called Dispersed Reference Compression(DRC), the coding scheme is changed according to the characteristic of the images to be compressed by Evolvable Hardware. Computation simulations experiment demonstrate that DRC provides compression rations that are up to 30% better than the current international standard for bi_level image compression, and which is also proved this method is effective. |
