说明：  通过拉普拉斯滤波器，高斯微分滤波器以及高斯差分滤波器提取图像边缘的简单matlab代码(Filter by Laplace, Gaussian derivative filters and difference filter from the edge of Gaussian simple matlab code)

for using this code need to use signal toolbox and general toolbox in your matlab Using Daubechies transform to compress the image (showing remaining coefficen of Thresholded Image) and then using Inverse 2D Daubechies transform and finding the SNR to see how well decompression works
