In this paper, a new approach for two-channel FIR "lter banks with low-delay and perfect-reconstruction (PR) properties is presented. The considered problem is formulated as the minimization of the real and imaginary parts weighted peak ripple errors of the designed analysis "lters subject to PR constraints. The dual a$ne scaling variant of Karmarkar's(More)
A two-phase fractal image sequence compression system is proposed. In the classification phase, according to the texture attribution a testing solid image block is assigned to its corresponding texture class. The texture attribution is derived from the tomographic block projection classification for the finite projection directions at the three-dimensional(More)
