An algorithm for image representation as independent levels of resolution

International audienceRecently it has been shown that natural images possess a special type of scale invariant statistics (multiscaling). In this paper, we will show how the multiscaling properties of images can be used to derive a redundancy-reducing oriented wavelet basis. This kind of representation can be learnt from the data and is optimally adapted for image coding; besides, it shows some features found in the visual pathwa
