This paper propose an efficient way to combine different spline types for computing first and second order derivatives (please see my video presentation). The following formula is derived, which shows that a spline surface can be rewritten as an outer product and a convolution Note that this equation is differentiable and this fact is used … Continue reading Image Derivatives
