The authors consider the problem of designing multiresolution transforms that are adapted to the given image signal, in the sense that they maximize the coding gain at each resolution level. A simple alternating optimization algorithm is derived for solving this problem in the framework of the lattice realization of para-unitary quadrature mirror filters. The resulting large coding scheme is discussed in some detail, and its performance is compared with that of the discrete cosine transform (JPEG) technique and with that of some nonadapted multiresolution transforms.>
