Description: DIGITAL IMAGERY is pervasive in our world today. Consequently,
standards for the efficient representation and
interchange of digital images are essential. To date, some of
the most successful still image compression standards have resulted
from the ongoing work of the Joint Photographic Experts
Group (JPEG). This group operates under the auspices of Joint
Technical Committee 1, Subcommittee 29, Working Group 1
(JTC 1/SC 29/WG 1), a collaborative effort between the International
Organization for Standardization (ISO) and International
Telecommunication Union Standardization Sector (ITUT).
Both the JPEG [1–3] and JPEG-LS [4–6] standards were
born from the work of the JPEG committee. For the last few
years, the JPEG committee has been working towards the establishment
of a new standard known as JPEG 2000 (i.e., ISO/IEC
15444). The fruits of these labors are now coming to bear, as
JPEG-2000 Part 1 (i.e., ISO/IEC 15444-1 [7]) has recently been
approved as a new international standard.-DIGITAL IMAGERY is pervasive in our world t oday. Consequently, standards for the efficient representation an d interchange of digital images are essential.

Description: This file contains a new and improved version of the Huffman coder, (June 29. 2001). The name is Huff06.m. There are also some additional files which are helpful when using Matlab for data compression: quantizer, different variants of run-length-encoding and end-of-block coding in Mat2Vec, and a program which do JPEG-like entropy coding. A complete compression example is shown in TestMat2Vec.m. This file is all you need for Huffman coding in MatLab.-This file contains a new and improved version of on of the Huffman coder, (June 29. 2001). The name is Huff06.m.

Description: RGB,YCbCr,HSV,HSL,CIE等颜色空间转换
这个Matlab程序用于颜色空间的转换。可以在RGB, YPbPr, YCbCr, YUV, YIQ, YDbDr, JPEG-YCbCr, HSV, HSL, XYZ, CIE Lab (CIELAB), CIE Luv (CIELUV), and CIE Lch (CIELCH)等颜色空间中任意转换。-B = colorspace( dest<-src , A) converts image A from color space src to color space dest .
Example:
B = colorspace( HSV<-RGB ,A) Convert image A from RGB to HSV
C = colorspace( YCbCr<-HSV ,B) Convert HSV to YCbCr
D = colorspace( RGB<-YCbCr ,C) Convert YCbCr back to RGB

Description: JPEG 静态图像压缩
各文件功能说明如下：
1) JPEG压缩程序：gendat.exe
2) 为压缩后的数据加上JPEG文件头的程序genjpg.exe
3) 解JEPG压缩程序extrdat.exe
其中：（1）的输入参量是需要生成的压缩文件的名字。
主程序流程为：
a) 程序初始化，读取文件名称、原始图像数据等基本数据；
b) 从AC.TAB和DC.TAB两个文件生成AC表和DC表，存入数组
c) 以8×8为样本单位进行DCT变换
d) 以8×8为样本单位进行量化
e) 以8×8为样本单位进行Z形扫描
f) 以8×8为样本单位进行熵编码
g) 以8×8为样本单位进行解量化
h) 以8×8为样本单位进行IDCT变换
-JPEG still image compression
Function of the documents as follows:
1) JPEG compression process: gendat.exe
2) For the compressed JPEG file header data, together with the procedures genjpg.exe
3) The solution JEPG compression program extrdat.exe
Of which: (1) the input parameters is the need to generate the compressed file s name.
The main program flow is:
a) procedures for initialization, read the file name, the original image data and other basic data
b) From the AC.TAB and DC.TAB two file generation AC table and DC table, into an array of
c) with 8 × 8 sample units for the DCT-
d) to 8 × 8 for the sample unit to quantify
e) to 8 × 8 for the sample units of Z-scan
f) to 8 × 8 for the sample units of entropy coding
g) to 8 × 8 for the sample unit to extract the quantitative
