Image enhancement using multiscale oriented wavelets
Additional Document Info
We describe a novel method of enhancing image geometric features using the oriented wavelets introduced in our early work . The poor directional selectivity of the conventional 2-D wavelet transform has been circumvented by using this class of oriented wavelets. By taking advantage of directional wavelet decomposition, both the directional and scale correlation information are utilized for enhancing salient structures in images. To remove phase dependence, a pair of quadrature filters are used. The proposed algorithm has been applied to chromosome image enhancement. Comparisons of this algorithm with other approaches are presented.
