为学习DCT而测试的bmp格式的文件转换为JPEG格式。水平有限，仅限初学者参考 用VC6.0开发-in order to study DCT, this programme is used to convert bmp format file into JPEG format. Only for beginners

两个l1准则下的噪声干扰信号压缩感知重构举例，两个例子的稀疏矩阵均为DCT矩阵，而观测矩阵分别采用单位阵和随机矩阵，有详细的步骤和使用方法，适用于初步的学习压缩感知方法。-This programme supply two examples by Compressed sensing with l1 norm. The sparse matrix of two examples are all DCT matrix and the obsever matrix are unit matrix a
