Image Compression A collection of simple routines for image compression using different techniques. 图象压缩的不同方法 BTCODE: Image compression Using Block Truncation Coding. PYRAMID: Image compression based on Gaussian Pyramids. DCTCOMPR: Image compression based on Discrete Cosine Transform. IMCOMPR: Image compression based on Singular Value Decomposition. The given codes can be also used in 2D noise suppression. Notes: The function "conv2fft" performs a 2D FFT-based convolution. Type "help conv2fft" on Matlab command window for more informations.

CodezBank is just a small application that stores source code snippets organized in a hierarhichal maner with basic search ability. You just copy and paste the code snippet into or from this application via clipboard. If you have a bag of coding tricks then you want to keep them in this app.

I ve written some many years ago dynamic Huffman algorithm to compress and decompress data. It is mainly targeted to data with some symbols occuring more often than the rest (e.g. having some data file consisted of 3 different symbols and their total number of occurence in that file s1(1000), s2(200), s3(30) so the total length of file is 1000+200+30=1230 bytes, it will be encoded assigning one bit to s1 and 2 bits to s2, s3 so the encoded length will be 1*1000+2*(200+30)=1460 bits=182 bytes). In the best case the file consisted of just one symbol will be encoded with compression ratio as 1:8. Huffman coding is used in image compression, however in JPEG2000 arithmetic codec is imployed.

misra (The Motor Industry Software Reliability Association 汽车工业软件可靠性联会) 是位于英国的一个跨国汽车工业协会，其成员包括了大部分欧美汽车生产商。其核心使命是为汽车工业提供服务和协助，帮助厂方开发安全的、高可靠性的嵌入式软件。这个组织最出名的成果是所谓的misra C Coding Standard，这一标准中包括了127条C语言编码标准，通常认为，如果能够完全遵守这些标准，则你的C代码是易读、可靠、可移植和易于维护的。最近很多嵌入式开发者都以misra C来衡量自己的编码风格，比如著名的uC/OS-II就得意地宣称自己99％遵守misra标准。
