Gabor wavelet FB is commonly utilised for a particular set of scales and orientations. ... The Gabor filter is a linear filter used for texture analysis, which essentially means that it analyzes whether there is any specific frequency content in the image in specific directions in a localized region around the point or region of analysis. See more In image processing, a Gabor filter, named after Dennis Gabor, who first proposed it as a 1D filter. The Gabor filter was first generalized to 2D by Gösta Granlund, by adding a reference direction. The Gabor filter is a See more Gabor filters are directly related to Gabor wavelets, since they can be designed for a number of dilations and rotations. However, in … See more A set of Gabor filters with different frequencies and orientations may be helpful for extracting useful features from an image.
