DoG Spot Detection

Manipulator

In the computer vision literature, this approach is referred to as the Difference of Gaussians (DoG) approach. Besides minor technicalities, however, this operator is in essence similar to the Laplacian and can be seen as an approximation of the Laplacian operator. In a similar fashion as for the Laplacian blob detector, blobs can be detected from scale-space extrema of differences of Gaussians (see http://en.wikipedia.org/wiki/Blob_detection#The_difference_of_Gaussians_approach).
