[Compress-Decompress algrithms] JPEG2000Compress_DecompressSourceCode DL : 1: 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.

[Compress-Decompress algrithms] Huffman_encode DL : 0: 这是一个霍夫曼编码的程序，是利用霍夫曼树等相关算法解决的。在程序中，随机产生的10个字符，利用子函数： HC=HuffmanCoding(HT,HC,w,3) 则可以获得每个元素的码字，存储的方式是通过一个指针的指针。-This is a Huffman coding process is the use of Huffman tree related algorithms to solve. In the process, the randomly generated 10 characters, using Functions: HC = HuffmanCoding (HT, HC, w, 3) are available for each element of the code words, storage is through a pointer.

[Compress-Decompress algrithms] Txt2Pdf_WithCompression_NoLIBs DL : 0: This program converts a plain TXT file to a plain text PDF file with compression. There is a file that I did not write in the project, a freeware ZLIB wrapper by Richard W. Frost (1998). However he used a .lib file while I use a consolidated .c file version of the ZLIB source, that I put together. The core text converter was not written by me initially I forgot the original author, but I modified it to handle compression.

[Compress-Decompress algrithms] losslessimagezipalgorithm DL : 0: 图像无损压缩算法代码全集,适合做图像无损压缩研究的入门人员收藏研究.-AR002 Contains a complete archiver by Haruhiko Okumura. The archiver uses an LZ engine whose output is compressed with static Huffman. The file is chopped into pieces which all get their own independent set of Huffman tree s. ARJ 2.41, ZIP 2.0 and PKZIP 2.04g use essentially the same method. ZOO and LHA even use excactly the same method. LZW The famous Lempel Ziv Welch compressor. This version by Kent Williams. COMP Arithmetic compression written by Mark R. Nelson. Published in Dr Dobbs february 1991. Contains a basic arithmetic compressor and a higher order arithmetic compressor. ASH A "brother" of the higher order compressor from Nelson written by Charles Ashford. Ingenious program which makes use of the very limited memory of the PC and still can process large files. One price to pay, it is VERY slow. The tigthest compressor in the Dr Dobbs compression contest. FIN Finish submission to the Dr Dobbs contest w

[Compress-Decompress algrithms] Matlab_Code_TAFGLSE_ISCIDE_2013 DL : 0: Texture-Aware Fast Global Level Set Evolution-Due to its intrinsic advantages such as the ability to automatically handle complex shapes and topological changes, the level set method has been widely used in image segmentation. Nevertheless, in addition to be computational expensive, it has the limitation to very often lead to a local minimum because of the energy functional to be minimized is non-convex. In this work, we use the geometric active contours and the image thresholding frameworks to design a novel method for global image segmentation. The local lattice Boltzmann method is used to solve the level set equation. The proposed algorithm is therefore effective and highly parallelizable. Experimental results on satellite, natural and medical images demonstrate the effectiveness and the efficiency of the proposed method when implemented using an NVIDIA graphics processing units The present Matlab code is the implementation of our work. For using: 1- Open the main code (TAFGLSE.m), 2- Put the adress of the image you w
