We present a technique for computing the convolution of an image with LoG (Laplacian-of-Gaussian) masks. It is well known that a LoG of variance a can be decomposed as a Gaussian mask and a LoG of variance a1 < a. We take advantage of the specific spectral characteristics of these filters in our computation: the LoG is a bandpass filter; we can therefore(More)
