You apply it to each image row, then on the result, on each image column. What separable means in this case is that you can write the spatial-domain filter as the outer product of two 1D filters. – Cris Luengo Aug 29, 2024 at 13:08 Add a comment 1 Answer
WebGabor filters are bandpass filters which are used in image processing for feature extraction, texture analysis [1] , and stereo disparity estimation [9,10,13-15,24,30] . The impulse response of these filters is created by multiplying an Gaussian envelope function with a complex oscillation.
