Multiple feature based multiscale image enhancement
L. Capdiferro, V. Casieri, Anna Laurenti, G. Jacovitti · 2003
A novel technique for image enhancement based on a multiscale pyramid is presented. It generalizes the classical edge-oriented wavelet based enhancement technique by employing multiple wavelet features. Visually relevant features are amplified in the wavelet domain according to a pointwise multiscale product. The use of complex in-phase/quadrature wavelets allows features, which are oriented any way, to be emphasized.
