Image Quality Estimation by Entropy and Redundancy Calculation for Various Wavelet Families

Abstract

In the present work we analyze the performance of orthogonal and biorthogonal wavelet filters for image compression on variety of test images. The test images are of different size and resolution. Three distortion measures are used: entropy of reconstructed image, energy retained and redundancy. Analysis is done on the basis of entropy and redundancy calculation and it is found that Biorthogonal wavelets are superior as compare to orthogonal ones.
