2014-09-19 08:54:15 -0600 | asked a question | Pixel tensors as matrix of matrices Hello! I want to calculate the structure tensor of an image, so I need to store one 2-by-2 matrix for each pixel of the image, and I am wondering what is the best way to do this. Optimally, I would like to be able to do But it fails with a segmentation fault when trying to create the 2-by-2 tensor I'm sure I'm just missing something trivial in one of the constructors, but I feel like I have tried everything! |
