Gabor filter texture analysis

Webthe output O(x, y). A properly designed Gabor filter can produce an output image O(x, y) exhibiting some types of discontinuity at the texture boundaries. When the two textures differ from each other, then one designs a Gabor filter that produces a step change in O(x, y) at the texture boundaries. 2.3 Parameter Selection of Gabor Filter WebGabor Filter Analysis for Texture Segmentation Michael Lindenbaum 2005 Abstract Gabor features are a common choice for texture analysis. There are several pop- ular sets of Gabor lters. These sets are usually designed based on representation considerations. We propose here an alternative criterion for designing the lters set.
