The J2000 codec was written in an effort to produce the cleanest and simplest implementation possible of the JPEG-2000 standard. We have put a particular emphasis on good architecture design and code simplicity, while at the same time providing an implementation as complete and efficient as possible ...

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 Grou ...

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 pro ...

这是06年4月刚刚完成的程序，从opencore.org下载而来。用vhdl语言描写，以及matlab仿真，testbench，以及在xinlinx上的综合。 The MDCT core is two dimensional discrete cosine transform implementation designed for use in compression systems like JPEG. Architecture is based on parallel distributed arithmetic ...

这个刚才那个的源代码，刚才弄错了。功能：可以从中得到bmp，jpeg，mpeg等的YUV，功能丰富

linux下将各类格式图片转换工具，包含bmp,jpeg,gif,ppm,jpg,pcx,png,ti

论文包括两个方面：离散余弦变换（DCT）的快速算法及滤波器实现结构，于波变换域图像门槛降噪。离散余弦变换是广泛应用于信号处理、图像处理领域的重要工具之一，己经被多个国际标准所接受，如JPEG、MPEG、H．263等。DCT应用到实际系统中的前提是具有能够快速实现的算法，自从1977第一个真正的DCT快速算法出现以来，寻求更 ...

离散余弦变换vc++代码，有测试图片和运行结果，在JPEG压缩中很有用。

实战粒子系统例程，一书的源代码，里面有一个JPEG Library的使用方法，很不错的。
