A flexible multiscale and directional representation for images is proposed. The scheme combines directional filter banks with the Laplacian pyramid to provides a sparse represent...
This paper is motivated by multichannel sampling applications. We consider a hybrid filter banks consisting of a set of fractional delays operators, slow A/D converters with differ...
—The JPEG 2000 image coding standard employs the biorthogonal 9/7 wavelet for lossy compression. The performance of hardware implementation of 9/7-filter bank depends on accuracy...
