摘要

Methods and devices for encoding and decoding images by implementing entrelau00e7amentos embedded, program, signal and corresponding application ".The invention relates to a method for encoding at least one image source using a hierarchical network by defining at least two embedded spaces, each one corresponding to a level DAnd the decomposition of the said entanglement, that is,At least one level of decomposition n (except for the first level of decomposition) in the distribution of coefficients of the image expressed in a basis of functions defined in a space ortogonaL the space corresponding to the level of decomposition before N - 1.The said functions being selected so that the so-called coefficients of image to the optimization of the said level of decomposition n of data already transmitted to the level of decomposition beforeN - 1, so as to produce a reconstructed image, which represents the image source, with the quality of restoration is optimized for said level of decomposition.
