[Ex(x,y),Ey(x,y)] T is the gradient of the image after folding with the 2D-smoothing filter G(x,y) = g(x)g(y) (as shown in =-=[7]-=-). Thus Deriche's approach can be seen as a gradient scheme. Deriche's optimal 1D-edge filter has the following impulse response function: f(z) = K e-ctlzl sin(toz), ct,to > 0. The two most interestin...
