Abstract
The application of spatially variant IIR (infinite impulse response) filter banks to subband image coding is reported. The new filter bank is based on computationally efficient recursive polyphase decompositions that dynamically change in response to the input signal. In the absence of quantization, reconstruction can be made exact. However, by proper choice of an adaptation scheme, it is shown that subband image coding based on time-varying filter banks can yield improvement over the use of conventional filter banks. Simulation results are presented.Keywords
