【摘要】 本算法是一种以二值图像格式高效率压缩保存包含多种单纯颜色信息的图像文件的压缩方法。该方法通过颜色分离、二值化处理等操作,可对包含有类似蓝色信笺头、红色公章、黑色图文等多种单纯颜色信息的影像文件以二值图像格式压缩保存,压缩效率比常用的8位以上彩色压缩方法提高8-10倍。在色彩种类少于7种的情况下压缩效果最明显。算法还包含相应的解压缩方法,还原后能原文原貌地恢复压缩前的图像和色彩内容。更多还原

【Abstract】 This is a compression method preserving efficiency by binary image format , and including variety of self-color information of image documents.Which can preserve variety of self-color information of image documents by the way of color seperation threshold processing,including of such as blue head letter paper, red official stamp or black image characters.The compression efficiency ratio commonly used 8 above colored compression method enhances 8-10 times.In the color type is short in 7 kind of situations reduces the effect to be most obvious.The algorithm also contains the corresponding solution compression method.The method can the original text original condition restore the image content.更多还原
