get_gradient

Axes considered for the gradient computation, as a C-string (e.g "xy").

axes

= Numerical scheme used for the gradient computation:
1 = Backward finite differences
0 = Centered finite differences
1 = Forward finite differences
2 = Using Sobel masks
3 = Using rotation invariant masks
4 = Using Deriche recursive filter.
5 = Using Van

scheme

Fast image processing for images in up to 4 dimensions (two spatial dimensions, one time/depth dimension, one colour dimension). Provides most traditional image processing tools (filtering, morphology, transformations, etc.) as well as various functions for easily analysing image data using R. 

get_gradient: Compute image gradient.
