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. The source code for the codec is freely available for anyone to study or even for use in commercial programs. We hope that our open development process and our focus on clean, straightforward code will help make the J2000 codec become a reference implementation of the JPEG-2000 standard

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.

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.

這是06年4月剛剛完成的程序，從opencore.org下載而來。用vhdl語言描寫，以及matlab仿真，testbench，以及在xinlinx上的綜合。 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 with butterfly computation.

論文包括兩個方面：離散余弦變換（DCT）的快速算法及濾波器實現結構，于波變換域圖像門檻降噪。離散余弦變換是廣泛應用于信號處理、圖像處理領域的重要工具之一，己經被多個國際標準所接受，如JPEG、MPEG、H．263等。DCT應用到實際系統中的前提是具有能夠快速實現的算法，自從1977第一個真正的DCT快速算法出現以來，尋求更快、更規則、更簡單的DCT快速算法一直是信號處理領域的一個研究方向。論文針對應用中對DCT長度的
