The multiscale CMPs are shown to approximate well the 1D angular Fourier transform of the band in question. This observation is used to derive further properties of the power spectrum in terms of texture orientations or n-folded symmetry patterns. A method is presented to approximate the power spectrum using only separable filtering in the spatial domain. Interesting implications to the Gabor decomposition are shown. The number of orientations in the filter bank is related to the order of n-folded symmetry detectable. Furthermore, the multiscale CMPs can be estimated incrementally in the spatial domain, which is both fast and reliable. Experiments on power spectrum estimation, orientation estimation, and texture segmentation are presented.</p> http://dx.doi.org/10.1364/JOSAA.24.000618 http://hh.diva-portal.org/smash/record.jsf?searchId=1&pid=diva2:239287 625 3 Journal of the Optical Society of America A Journal Paper 618 Multiscale complex moments of the local power spectrum 24 2007 2016-09-30T20:40:36Z 2457662.3615278 Multiscale complex moments of the local power spectrum 500 0 plainlist list 1 [[:Publications:Multiscale complex moments of the local power spectrum]] Multiscale complex moments of the local power spectrum# QUERY48817f4a7f667913a0e059019db5f8a6 500 [2,"smw-datavalue-property-restricted-annotation-use","Publisher"] Multiscale complex moments of the local power spectrum# ERR6c155b5d70b69ddb590b4f2e73389c2a 500 [2,"smw-datavalue-property-restricted-annotation-use","Author"] Multiscale complex moments of the local power spectrum# ERRe24f17e090c98448f3de99d03182b7b6
