GaborFilter
GaborFilter[image, r, k]
filters image by convolving with a Gabor kernel of pixel radius r and wave vector k.
GaborFilter[image, r, k, 
]
uses a Gabor kernel with phase shift .
GaborFilter[image, {r, 
}, ...]
uses a Gabor kernel with radius 
and standard deviation .
GaborFilter[data, ...]
applies Gabor filtering to an array of data.
Details and Options
- GaborFilter is a linear filter commonly used for edge detection, as well as local frequency and orientation analysis.
- GaborFilter works with arbitrary grayscale or multichannel images, operating separately on each channel.
- GaborFilter works with 3D as well as 2D images, and also with data arrays of any rank.
- GaborFilter[image, r, k] is equivalent to GaborFilter[image, {r, r/2}, k, 0].
- GaborFilter allows any of r and to be lists, specifying different values for different directions.
- GaborFilter[image, ...] by default gives a real image of the same dimensions as image.
- GaborFilter can take the following options:
-
Padding "Fixed" padding method WorkingPrecision Automatic the precision to use "Standardization" True whether to rescale the Gabor kernel to account for truncation - With a setting Padding->None, GaborFilter[image, ...] normally gives an image smaller than image.
