Abstract

This work proposes a new approach to increase the quality of natural images by compressing the images into large extent. The proposed scheme is used on different types of families of wavelets and experiments on Matlab are done using wavelet transform. Different compression algorithms are also applied for best results. Quality estimation is done on the basis of entropy calculation. However other parameters like compression ratio, peak signal to noise ratio and energy retained are also calculated for comparison these wavelet families.
