hscharr

hscharr

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

Deprecated function. Use skimage.filters.scharr_h instead.

Find the horizontal 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   10   3
 0    0   0
-3  -10  -3
