vscharr

vscharr

skimage.filters.vscharr(*args, **kwargs) [source]

Deprecated function. Use skimage.filters.scharr_v instead.

Find the vertical edges of an image using the Scharr transform.

Parameters:	image : 2-D array Image to process mask : 2-D array, optional An optional mask to limit the application to a certain area. Note that pixels surrounding masked regions are also masked to prevent masked regions from affecting the result.
Returns:	output : 2-D array The absolute Scharr edge map.

Notes

We use the following kernel and return the absolute value of the result at each point:

 3   0   -3
10   0  -10
 3   0   -3
