My projrect is hiden text and pdf in image using Wavelet algortihm based of haar wavelet , daubeches, coiflet and legendre wavelet, which the good algorithm based?
Dear Aldo:
It suppose that you start with one of the theories you mentioned above and then after finding the results compare with another once from the list above. From my experience that first two algorithms are more related to differential and integral source of data, while the other last two are related to polynomial behaviour.
