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.

This implementation was contributed as a paper to the Insight Journal http://hdl.handle.net/1926/500

const [virtual]

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.
