基于stm32的jpeg图片压缩代码，并且通过串口输出(The stm32-based jpeg image compression code, and output through the serial port)

Jepg2000的压缩解压(Jepg2000 compression decompression)

 用霍夫曼编码实现的简单的文本压缩解压缩C++源程序

说明：  A Visual Cryptography Based Watermark Technology for Individual

实现图像的jpeg无损压缩，可以在linux系统下经过交叉编译器编译后在arm上实现，已经写好makefile文件(Realize jpeg image lossless compression, you can linux system through cross-compiler to compile in the arm to achieve, has written makefile file)

说明：  对测试图像分块、DCT和量化，将量化后的系数写成矩阵形式。(The test image block, DCT and quantization, the quantized coefficients written in matrix form.)

16字节字符串压缩成12字节字符串算法，有压缩和解压的算法(16-byte string into a 12-byte string compression algorithm, compression and decompression algorithms)

说明：  GPS C/A码捕获 用的是fft频域的搜索 有C/A码产生和C/A码数字化子程序，模拟卫星信号的捕获算法和过程，未考虑多普勒频移(GPS C/A code acquisition in frequency domain using the fft search with C/A code generation and C/A code number of subroutines, analog satellite signal acquisition method and process, without considering the Doppler shift)

压缩感知，对一维信号进行压缩感知，并还原信号。(Compressed sensing, the one-dimensional signal compressed sensing, and redox signaling)

ffmpeg 是一个开源、功能强大的多媒体处理软件，可以实现对音频流、视频流的录制和转换。(ffmpeg is an open source, powerful multimedia processing software, which enables audio streaming, video streaming recording and conversion.)
