提示: JPEG压缩分为三个部分: 1.JPEG压缩原理及算法(RGB/YCbCr,DCT/IDCT,量化,Z字型编码,用DPCM对DC/用RLE对AC编码/Huffman编码) 2.JPEG标记格式 3.JPEG图片文件的组织形式(位于SOS后的图像压缩数据是由MCU块怎样排列的,特别是使用了DRI之后) 还有许多细节问题: 1.解码过程中遇到“FF 00”当“FF”处理,否则忽略“FF” 2.进行DCT前YCbCr要减128,进行IDCT前要加128(相当于Y减128,YCbCr不需要加12

算术编码是图像压缩的主要算法之一。 在给定符号集和符号概率的情况下,算术编码可以给出接近最优的编码结果。使用算术编码的压缩算法通常先要对输入符号的概率进行估计,然后再编码。这个估计越准,编码结果就越接近最优的结果-Arithmetic coding algorithm was a major one compressed image. In a given symbol set and symbol probability case, arithmetic coding can give nea

提出的算法可以解决在嵌入式系统上显示含有文本和图像的PDF 文件的要求。该算法先将PDF 文件分解成图像和文本两部分,然
后依照原文件的显示格式将分解出来的元素合成一种新的格式文件,最终实现将PC 机上的PDF 格式文件转化为适合在嵌入式系统上正确显示的格式。该算法缩减了文件的大小,使之适应于嵌入式系统有限的硬件资源,也扩大了嵌入式系统的文件来源。-The proposed algorithm can solve embedded system with text and images di
