WebTomasi, 1994), but the one deﬁning the Harris corner detector is maybe the most commonly employed. The Hessian matrix has been also used to design keypoint detectors according to its determinant (Beaudet, 1978). Di erently from the Harris cor-ner detector, the SIFT detector is based on the ﬁlter response to DoG, as approximation of the ...
