How to take the gradient of a function

Webtorch.gradient. Estimates the gradient of a function g : \mathbb {R}^n \rightarrow \mathbb {R} g: Rn → R in one or more dimensions using the second-order accurate central differences method. The gradient of g g is estimated using samples. By default, when spacing is not specified, the samples are entirely described by input, and the mapping ... WebAug 28, 2024 · 2. In your answer the gradients are swapped. They should be edges_y = filters.sobel_h (im) , edges_x = filters.sobel_v (im). This is because sobel_h finds horizontal edges, which are discovered by the derivative in the y direction. You can see the kernel used by the sobel_h operator is taking the derivative in the y direction.
