Matlab implementation of image compression based on two level wavelet transform
no vote
Matlab to achieve two-level wavelet decomposition of image compression, using bior3.7 wavelet basis to achieve two-level wavelet transform, and then using Matlab's own function wcodemat to achieve the first and second level image compression, and calculate the compression ratio, mean square error, peak signal-to-noise ratio before and after image compression
