Wavelet transform is becoming more and more important in image compression applications because of its suppleness in on behalf of non-stationary signals. Current techniques use comprehensive search trial that are computationally rigorous to find the "optimal" basis. In this paper, we offer some guiding principle based on the statistics of the image to be coded, for formative the need to search for the "optimal" wavelets as well as the development that can be achieved by using the "optimal" over "standard" wavelets. The proposed guidelines can be used to find a good initial guess for the exhaustive search if the optimal basis is needed.

A New Robust Pre-Processing Technology of Image Compression based on Wavelets Decomposition
