Abstract
A method for optimizing signal quantification comprising applying reversible filters to the signal in order to pre-quantify the signal as a continuous function of the frequency domain; pre-processing the signal in order to place it in the proper colorspace and frequency domain; applying subband transforms to the signal in order to split the signal into frequency regions; and entropy coding the signal. Additionally filters and steps are also provided that enable improved quantification of the signal resulting in improved compression of the resulting signal.
