所有LSB算法的代码实现。对做信息隐藏方面很有帮助(LSB algorithm code. Hidden aspects helpful to do information)

A simple function that takes an image and a mask as the input, perform compression and decompression on the image (color image compression if input image is color), and display the original and reconstructed images side by side. The program should also be able to compute the SNR of the reconstructed image.
