摘要
The 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 (C) 2010 Elsevier BV All rights reserved
