Abstract
We develop a higher dimensional version of the Canny edge detection algorithm. The Canny operation detects the zero-crossing of the gradient of the Gaussian-convolved image. The segment edge curve detected by the Canny operation is an approximation of zero-crossing of bilinear form defined by second order derivative of an image. This definition of edge points of segment is dimension independent. This definition also allows us to extend the filtering operation from the Gaussian convolution to general linear and non-linear ones.
