Laplacian

Categories: Pattern Recognition and Image Processing


Author(s): T.P. Pridmore, S.R. Pollard, S.T. Stenton

The Laplacian is the lowest (second) order circularly symmetric differential operator. When convolved with a 2D function (e.g., an image) it computes the non-directional second derivative of that function. See also Convolution.
