WebIn image processing, there are a few low-level examples of the use of Log-Gabor filters. Edge detection is one such primitive operation, where the edges of the image are labeled. Because edges appear in the frequency domain as high frequencies, it is natural to use a filter such as the Log-Gabor to pick out these edges. ... WebGabor filters are used as detectors of small, localized cloud stretches or blobs in the satellite image. As these detectors are localized, a large number of Gabor filters are used to cover the whole image (the exact number depends on the size of the image and the size of each filter's receptive field). ... edge detection, segmentation, or ...
