Abstract:
According to the present invention, multiresolution decomposition is performed on a color component of image data by using a wavelet frame with orientation selectivity or a filter bank with orientation selectivity and subband signals are obtained; and when reconstructing an image by summing the obtained subband signals, coefficient processing is performed, between a decomposition phase and a synthesis phase in the multiresolution decomposition, on decomposition detail coefficients that are output from the decomposition phase such that the larger the energy of the decomposition detail coefficients is, the more small values are further reduced, and the smaller the energy of the decomposition detail coefficients is, the more small values are increased, or vise versa.
Abstract:
When obtaining subband signals by performing multiresolution decomposition on image data using a broad-sense pinwheel framelet or a pinwheel wavelet frame, having a degree, that is a set of an approximate filter with no orientation and a plurality of detail filters with respective orientations, and acquiring processed image data by the subband signals in a decomposition phase of the multiresolution decomposition, or processed image data that has been reconstructed into an image by summing the subband signals in a synthesis phase of the multiresolution decomposition, the present invention performs attenuation or amplification of the subband signals in the decomposition phase of the multiresolution decomposition that correspond to at least one of the filters.

Abstract:
In the present invention, subband signals are obtained by performing multiresolution decomposition on image data by using a broad-sense pinwheel framelet that is a set of an approximate filter with no orientation and a plurality of detail filters with respective orientations, and that has a degree. When an image is reconstructed by summing the obtained subband signals, the reconstructed image data is generated by attenuating or amplifying a subband signal corresponding to at least one of filters that have predetermined frequency characteristics and/or a predetermined orientation among the filters.
