Abstract :
In order to get good fusion result for nomadic service under pervasive computing paradigm, based on our researches, we present a new approach of entropy-based wavelet filtering to do an adaptive soft process for nomadic decision, which is the good balance when considering both application quality and the PSNR criterion. Using a hard threshold-ing, a soft thresholding , MEF method, and MEF method with as a function of the SNR, wavelet coefficient can be modified . Our project has been provided evidence of feasibility of the a new approach.
