HI,I read the code about the _get_xsobel_coord in watermark_reconstruct.py As we know ,the sobel is as follows: image But ,the function in _get_xsobel_coord and _get_ysobel_coord is different form this. _get_xsobel_coord uses the sobely and _get_ysobel_coord use a usually kenerl. Why ? could you please talk about this?

the function _get_ysobel_coord use Gx and the function _get_xsobel_coord use a unusual kernel
