Abstract

The problem of easily implementable filter bank design for subband coding is discussed. A technique is proposed to generate filter banks with coefficients in powers-of-two and with maximum localization. The hierarchical structure of the filter bank is then used to eliminate the temporal redundancies by using a multiresolution motion estimation technique. Simulations show a robust estimation of the motion field with a relatively simple implementation.
