摘要
The relevance of the local phase information for texture discrimination and image segmentation is studied. Useful local phase information is obtained by unwrapping the phase images which result from the application of 2D Gabor filters, i.e., with both a frequency and an orientation selectivity. The unwrapping method applied is based on phase demodulation, where the global linear phase component in the orientation of the filter is directly measured from the wrapped phase image. Experimental results seem to confirm the importance of the local phase information. © 1990.
