摘要
二值化简单彩色图像压缩方法通过颜色分离、二值化处理等操作,以二值图像格式高效率压缩保存包含有类似蓝色信笺头、红色公章、黑色图文等单纯颜色信息的影像文件,而且还原后能够原文原貌地恢复压缩前的图像和色彩内容,压缩效率比常用的8位以上彩色压缩方法提高8～10倍。二值化简单彩色图像压缩方法压缩7种以下单纯颜色图像文件的效果最为明显。
A binarization simple color image compression method can preserve 6-7 kinds of pure color information of image documents by the way of color separation,binarization processing operations,such as blue head letter paper,red official stamp or black image characters.The compression efficiency ratio enhances 8~10 times by comparing with commonly 8 above colored compression method.In the color type is short in 7 kinds of situations reduces the effect to be most obvious.
