The Gabor filter is a linear filterused for textureanalysis, 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 general, expansion is not applied for Gabor wavelets, since this requires computation of bi-orthogonal wavelets, which … See more A set of Gabor filters with different frequencies and orientations may be helpful for extracting useful features from an image. In the … See more This is an example implementation in Python: For an implementation on images, see [1]. This is an example implementation in MATLAB/Octave: Code for Gabor feature extraction from images in See more Its impulse response is defined by a sinusoidal wave (a plane wave for 2D Gabor filters) multiplied by a Gaussian function. Because of the multiplication-convolution property (Convolution theorem), the Fourier transform of a Gabor filter's impulse response … See more When processing temporal signals, data from the future cannot be accessed, which leads to problems if attempting to use Gabor functions for … See more In document image processing, Gabor features are ideal for identifying the script of a word in a multilingual document.
