图像压缩算法，matlab环境编写，包括：btcode，conv2fft，convfft，dctcompr，imcompr，pyramid，都是很经典的哦：）-image compression algorithm, Matlab environment preparation, including : btcode, conv2fft. convfft, dctcompr, imcompr, pyramid, very classic oh :)

ase read your package and describe it at least 40 bytes. System will automatically delete the directory of debug and release, so please do not put files on these two directory.

- conv2fft.m ---> M-file for 2D FFT-based convolution - convfft.m ---> M-file for 1D FFT-based convolution-- conv2fft.m ---> M-file for 2D FFT-based convolution - convfft.m ---> M-file for 1D FFT-based convolution
