#include <itkGaborKernelFunction.h>
Gabor kernel used for various computer vision tasks.
This class encapsulates a complex Gabor kernel used for various computer vision tasks such as texture segmentation, motion analysis, and object recognition. It is essentially a complex sinusoid enveloped within a Gaussian. See the discussion in
Andreas Klein, Forester Lee, and Amir A. Amini, "Quantitative Coronary Angiography with Deformable Spline Models", IEEE-TMI 16(5):468-482, October 1997.
for a basic discussion including additional references.
This implementation was contributed as a paper to the Insight Journal https://doi.org/10.54294/dhogdz
