as I searched gabor filter is most used tool on texture analysis and edge detection in digital image. its said that it searches a certain frequency as a texure around a pixel or point to find the texture. I cant really understand it well. as I know frequency in digital image is sign of change in grayscale change. high frequency has high change in grayscale so a highpass filter finds the edges but I cant understand a filter like gabor can find a special texture.
thank you for helping
