加密解密 除了上面提到的压缩方法
除了上面提到的压缩方法,你也可以调用VB的工具MakeCab.exe(在VB5\setupkit\kitfil32或VB98\Wizards\PDWizard目录下)生成.cab文件。先构造一个Directive 文件(*.ddf),然后使用Shell命令调用MakeCAB /f excel.ddf就可以生成*.cab文件。关于Directive 文件的格式,可以参考MSDN Library中的《MakeCAB: A Compression and D ...
语音压缩 The Audio File Library provides a uniform programming interface to standard digital audio file form
The Audio File Library provides a uniform programming interface to
standard digital audio file formats.
This library allows the processing of audio data to and from audio
files of many common formats (currently AIFF, AIFF-C, WAVE, NeXT/Sun
.snd/.au, IRCAM, AVR, Amiga IFF/8SVX, and NIST SPHERE). The ...

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

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 ...
VHDL/FPGA/Verilog 这是06年4月刚刚完成的程序
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 ...

Wavelets have widely been used in many signal and image processing applications. In this paper, a new
serial-parallel architecture for wavelet-based image compression is introduced. It is based on a 4-tap wavelet
transform, which is realised using some FIFO memory modules implementing a pixel-level ...
