journal contribution
posted on 2023-06-08, 06:49 authored by Phil BirchPhil Birch, Bhargav Mitra, Nagachetan M Bangalore, Saad Rehman, Rupert YoungRupert Young, Chris ChatwinChris ChatwinThe Difference of Gaussian (DOG) filter is widely used in optics and image processing as, among other things, an edge detection and correlation filter. It has important biological applications and appears to be part of the mammalian vision system. In this paper we analyse the filter and provide details of the full width half maximum, bandwidth and frequency response in order to aid the full characterisation of its performance. © 2010 Elsevier B.V.
