- % RES = pyrBand(PYR, INDICES, BAND_NUM)
- %
- % Access a subband from a pyramid (gaussian, laplacian, QMF/wavelet,
- % or steerable). Subbands are numbered consecutively, from finest
- % (highest spatial frequency) to coarsest (lowest spatial frequency).
- % Eero Simoncelli, 6/96.
- function res = pyrBand(pyr, pind, band)
- res = reshape( pyr(pyrBandIndices(pind,band)), pind(band,1), pind(band,2) );
