Abstract :
A gradient-based edge detection scheme for pervasive computing is proposed, which is deduced from Fresnel diffraction. It is a pair of 3 times 3 convolution kernels for measuring horizontal and vertical gradients. While the new method can gives quantitative results equal to the Canny detector while it is simple. So it is more suitable for different kinds of computing platforms.
