imgradient: Compute image gradient
In imager: Image Processing Library Based on 'CImg'
imgradient R Documentation
Compute image gradient
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"
Author(s)
Simon Barthelme
Examples
grayscale(boats) %>% imgradient("x") %>% plot
imgradient(boats,"xy") #Returns a list
