  1. The Gabor filter, named after Dennis Gabor, is a linear filter used in myriad of image processing application for edge detection, texture analysis, feature extraction, etc.[1]
  2. Gabor filters are special classes of band pass filters, i.e., they allow a certain ‘band’ of frequencies and reject the others.[1]
  3. A Gabor filter can be viewed as a sinusoidal signal of particular frequency and orientation, modulated by a Gaussian wave.[1]
  4. When the input image is convolved with all the Gabor filters the patterns are easily highlighted as shown in figure 3.[1]
  5. The Log-Gabor filter is able to describe a signal in terms of the local frequency responses.[2]
  6. Indeed, any application that uses Gabor filters, or other wavelet basis functions may benefit from the Log-Gabor filter.[2]
  7. Features formed from the response of Log-Gabor filters may form a good set of features for some applications because it can locally represent frequency information.[2]
  8. Because of this, the Gabor filter is a good method for simultaneously localizing spatial/temporal and frequency information.[2]

  19. A raster or matrix to be filtered lamda Wavelength of the cosine part of Gabor filter kernel in pixel.[8]
  20. This is the wavelength of the cosine factor of the Gabor filter kernel and herewith the preferred wavelength of this filter.[9]
