One of the mostuseful popular applications of computers nowadays involve picturemodifications like enhancing colors or including blur or contrasteffects. In computer vision, the Marr-Hildreth algorithm is a method ofdetecting edges in digital images, that is continuous curves where thereare strong and rapid variations in image brightness. The Marr-Hildrethedge detection method is simple and operates by convolving the imagewith the Laplacian of the Gaussian function, or, as a fast approximationby Difference of Gaussians. Then, zero-crossings are detected in thefiltered result to obtain the edges. The Laplacian of the Gaussian imageoperator is sometimes also referred to as the Mexican hat wavelet due toits visual shape when turned up-side-down. David Marr and Ellen C.Hildreth are two of the inventors.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 92 pp. Englisch. Nº de ref. del artículo: 9786131390715
