如何将Gabor小波应用于3D体积？

Question

I'm looking for a way to apply the Gabor wavelet function to a volume to extract small veins from it.

I've got a 3D Gabor filter creator from here .

These are my parameters:

gabor3_fwb([1 1], [pi/4 pi/4], 10, 0, 20);

Also my image is 150x150x150 double

This is my filter:

Given your image image and your Gabor kernel kernel , you simply convolve the two to obtain a filtered image:

 result = convn(image, kernel, 'same');

Since kernel is complex-valued (if it is not, your Gabor generator is wrong), result will be complex-valued too. One typically uses the magnitude of the result:

result = abs(result);
