Abstract :
This paper describes key issues associated with the computation of undecimated multiresolution signal decompositions. An effective solution is obtained by a general-purpose convolution programming model that automatically accounts for filter origin displacement and the sparse nature of upsampled filters. The handling of image boundaries during convolution is also discussed in detail
