When we take derivatives to x (spatial derivatives) of the gaussian function repetitively, we see a pattern emerging of a polynomial of increasing order, multiplied with the original (normalized) gaussian function again.
Gaussian Filter Derivative The derivation of a gaussian blurred input signal is identical to filter the raw input signal with a derivative of the gaussian. in this subsection the 1 and 2 dimensional gaussian filter as well as their derivatives are introduced. This is the direct implementation of the definition of the discrete convolution using the fact that the gaussian function is seperable and thus the 2d convolution can be implemented by first convolving the image along the rows followed by a convolution along the columns. The gaussian derivatives are characterized by the product of a polynomial function, the hermite polynomial, and a gaussian kernel. the order of the hermite polyno mial is the same as the differential order of the gaussian derivative. So far we’ve seen how derivatives of gps are defined, and how to draw from the joint distribution of a gp and its derivative. in future posts we’ll look at fitting gps in stan with derivative observations, and at shape constrained gps.

The paper presents a novel approach to recursively implement the gaussian function and its derivatives. it explores the mathematical foundations and computational strategies to improve efficiency in calculations, addressing common challenges faced in traditional implementations. I.e. you start with the exponent of the exponential function (derive it), then comes the exponential function itself with the derived argument as argument for the next derivation, then comes the derivation of the whole square bracket, and finally the result is simplified in the last two lines. Option 1: reconstruct a continuous image, f, then compute the derivative option 2: take discrete derivative (finite difference). When we take derivatives to x (spatial derivatives) of the gaussian function repeti tively, we see a pattern emerging of a polynomial of increasing order, multiplied with the original (normalized) gaussian function again. here we show a table of the derivatives from order 0 (i.e. no differentiation) to 3. in[3]:= out[4] tableform=.
