Gabor image processing
WebNevertheless, the Log-Gabor filter has been shown to be particularly useful in image processing applications, because it has been shown to better capture the statistics of natural images. In image processing, there are a … Webi.gabor computes texture raster maps from a user-specified Gabor filter bank and raster map. The 2 dimensional Gabor filter is an orientation sensitive filter which mimics the cells within the human visual cortex by creating a filter bank of multiple orientations and scales to pick up different frequency responses.
