Description
Light interface for get_gradient. Refer to get_gradient for details on the computation.
Usage
imgradient(im, axes = "xy", scheme = 3)
Arguments
im |
an image of class cimg |
axes |
direction along which to compute the gradient. Either a single character (e.g. "x"), or multiple characters (e.g. "xyz"). Default: "xy" |
scheme |
numerical scheme (default '3', rotation invariant) |
Value
an image or a list of images, depending on the value of "axes"
