Detailed Description

template<typename TRealValueType>
class itk::GaborKernelFunction< TRealValueType >

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.
