The line echo canceller (LEC) is designed to provide the maximum attainable transparent voice quality for de-echoing of a PSTN or POTS connection in voice-over-LAN systems with internal delays, or on a codec end of a telecom switch,基于TI 54X/55X平臺(tái)

Jpeg2000編解碼器，附VC、Delphi等常用編程語言的使用例程 J2K-codec ver 1.9 === === === === === === === === ===== Make your graphics look better with an easy-to-use JPEG 2000 decoding component. J2K-codec can help game developers, screensaver creators and many others to improve their products--to achieve better image quality and reduce installation package size. The new image compression standard based on wavelet technology has many interesting features not available in the old JPEG, such as alpha-channel and varied resolution levels.

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.
