Log-Gabor filters basically consist in a logarithmic transformation of the Gabor domain which eliminates the annoying DC-component allocated in medium and high-pass filters. Fig. 1: Profiles of the frequency response of Gabor filters (left) and log-Gabor filters (right).

Log Gabor filter. In signal processing it is useful to simultaneously analyze the space and frequency characteristics of a signal. While the Fourier transform gives the frequency information of the signal, it is not localized. This means that we cannot determine which part of a (perhaps long) signal produced a particular frequency.
The proposed algorithm creates log-Gabor Filters, which is often used to denoise images.
Oct 31, 2015 · What you are getting is the visualization of the Gabor Filter you are using. You need to apply this filter to the retina image to get the image you want. – skytreader Nov 7 '13 at 2:56. oh oh k sir…i will try doing it…thanks a lot sir – vidya Nov 7 '13 at 4:47.
identification based on image processing bring more attention. In particular, vehicle verification is especially challenging on account of the heterogeneity of vehicles in color, size, pose, etc. Image based vehicle verification is usually addressed as a supervised classification … Log Gabor Filter Based Feature Detection in Image …
