Light interface for get_gradient. Refer to get_gradient for details on the computation.
imgradient(im, axes = "xy", scheme = 3)
an image or a list of images, depending on the value of "axes"
an image of class cimg
direction along which to compute the gradient. Either a single character (e.g. "x"), or multiple characters (e.g. "xyz"). Default: "xy"
numerical scheme (default '3', rotation invariant)
Simon Barthelme
cimg.limit.openmp() grayscale(boats) %>% imgradient("x") %>% plot imgradient(boats,"xy") #Returns a list
