Find the vertical edges of an image using the Sobel 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.

The absolute Sobel edge map.

Notes

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

1   0  -1
2   0  -2
