Path: Imaging/ImageMatching
% Generate an image derivative using a Gaussian kernal. This does derivatives in two directions in both x and y. Since version 8. -------------------------------------------------------------------------- Form: GaussianDerivative; d = GaussianDerivative( q, sigma, eps ) -------------------------------------------------------------------------- ------ Inputs ------ q (n,m) Grayscale image sigma (1,1) Standard deviation of the Gaussian kernal eps (1,1) Epsilon ------- Outputs ------- dX (n+4,m+4) Derivative in the x direction dY (n+4,m+4) Derivative in the y direction --------------------------------------------------------------------------
