Derivate

Node Icon

An image derivative filter is a mathematical operation that is applied to an image to extract information about its edge or texture features. It calculates the gradient or rate of change of the intensity values in the image and outputs a map of the derivative values. The results of the filter can be used for tasks such as edge detection, feature extraction, and image segmentation. This filter calculates the n:th order derivative image of an input.
