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128) 3.每个标记中数据可以不止一个(去掉长度的部分就是一段)-Tip : JPEG compression is divided into three parts : Principles and 1.JPEG compression algorithm (RGB/YCbCr, DCT/IDCT, quantification, Z-shaped coding, using the DPCM DC/AC with RLE encoding/Huffman coding) 2.JPEG tags 3.JPEG Photo paper form (located in the SOS image data is compressed by the MCU to set pieces, particularly after the use of DRI), there are many details : 1. decoding process encountered "FF 00," when the "FF", otherwise overlooked "FF" 2 .DCTYCbCr128IDCT128Y128YCbCr128 3.

数字图像处理源程序vc++
图像的点运算主要用来改变图像的灰度分布范围;点运算的最大特点是输出像素值只与当前输入像素值有关,本文主要介绍利用灰度直方图查看图像信息,了解各种灰度变换公式,掌握灰度变化实现方法。

水平集图像处理程序,我们提出了一个新的变分公式
水平集图像处理程序,利用一个新的变分公式进行图像处理,效果很好-Level set image processing program,we present a new variational formulation
for geometric active contours that forces the level set function
to be close to a signed distance function, and therefore
completely eliminates the need of the costly re-initialization
procedure.

With this tool you can convert strings and files containing XML data to MATLAB struct arrays. Either as one array of structs with all text and tags, or as sub- and subsub-levels of structs for each section enclosed between tags.
With xmldata(...) is a "fast" lowlevel interface to read single tags. Compiled mex-files for Linux & Windows. c-source included.
