Commented: vibhor vishnoi on 29 Mar What are the features we can extract using gabor filtering for images histopathological image is the mean value from the orientation will be extracted or any other features apart from it.. Cancel Copy to Clipboard. Gabor Filters are very effective to extract texture feature and their analysis. Accepted Answer. If you are using a set of Gabor filters with different orientations and frequencies, then you have a host of features you can extract.

A Gabor filter is essentially a sinusoidal signal with a given frequency and orientation, modulated by a Gaussian. You can use it for edge and object detection, image representation and coding, color or pattern gradient, etc. Subha on 3 Mar Walter Roberson on 3 Mar The second and third sublists are the imaginary and real part of the image resulted after the convolution with the gabor filters. The following code chunk allows the user to plot the different scales and orientations of the image,.

The dat object is a list of length 2. The first sublist corresponds to magnitude whereas the second sublist to local-energy and mean-aptitude. By averaging both the gabor and the HoG features the mean accuracy increases to
