The convolution is performed by sliding the kernel over the image, generally
starting at the top left corner, so as to move the kernel through all the ...
A jet is a condense and robust representation of a local grey value distribution.
It is based on a Gabor wavelet transform, which is a convolution with a ...
A 2D Gabor kernel can be mathematically defined as:
where
The parameters involved in the construction of a 2D Gabor filter are:
• The variance of the gaussian function
• The wavelength of the sinusoidal function
• The orientation of the normal to the parallel stripes of the Gabor function
• The spatial aspect ratio specifies the ellipticity of the support of the Gabor function. For , the support is circular. For the support is elongated in the orientation of the parallel stripes of the function.
