DoG filters have been used previously in marnmographic mass computer-aided detection (CAD) systems. As DoG filters are constructed from the subtraction of two bivariate Gaussian distributions, they require the specification of three parameters: the size of the filter template and the standard ...
Satellite imagery provides a useful means of mapping various sand dune types in the sand fields. However, the texture and composition of dunes is usually not clear on the images. In order to enhance textural and spatial features of the dunes, difference of Gaussian (DOG) filters were applied ...
The two filters are related, however, as illustrated by Fig. 2(c–e). Some previous works in artistic thresholding [6], [10] employ the DoG operator as part of a complex processing pipeline, though an equivalent effect can be achieved with a simple extension to the DoG operator itself (...

In view of the problem that the noise and occlusion in stereo matching may bring some ambiguous points,a new stereo matching algorithm based on DoG is proposed in this paper.Firstly it calculates disparity map using the Sum of Absolutes(SAD) in the original image,then a threshold map can be...

A method of designing filters for filtering digitized images includes constructing a set of difference-of-Gaussian (DoG) filters that partition a frequency space, forming a linear combination of said DoG filters to form a trial filter, convolving said trial filter with a training image to obtain...

This paper proposes a method for detection of microcalcification clusters in mammograms using sequential Difference of Gaussian filters (DoG). In a first stage, fifteen DoG filters are applied sequentially to extract the potential regions, and later, these regions are classified using the following ...
