处理图像lena.bmp,并画出各图像的灰度层次的分布图，并对256位和16位信源数据进行霍夫曼编码-lena.bmp image processing and paint images of the gray level of distribution map as well as 256-bit and 16-bit data source coding Hoffman

fractal image compression of gray scale images.... only works for square images... try with lena.bmp a gray scale one.... good compression ratio acheived

用c将bmp文件打开并转成raw格式,图像是lena-use c++ to open bmp images and change it to raw images.

matlab 写的 压缩感知的程序，基于压缩感知 + bp + omp + mp 对 lena.jpg 256*256 图片进行采样和还原，仿真了还原的效果，对不同snr下的还原效果进行研究和仿真-Compressed sensing program matlab write, based on compressed sensing+ bp+ omp+ mp lena.jpg 256* 256 images on sampling and restore, restore the simulat
