Simply in the use of records
Sobel () operator is an image processing for edge detection
Opencv-python in functional form as
def Sobel(src, ddepth, dx, dy, dst=None, ksize=None, scale=None, delta=None, borderType=None):
src: the source image
ddepth: the depth of the target image (ps: Depth is valid again), if -1 is the same as the source image depth
dx, dy: the current direction of the directional derivative of the series, ranging typically 0,1, 2
dst: destination image
ksize: kernel size is generally 1,3,5,7
Scale: I do not know Gansha use of
delta: do not know doing with
borderType: also do not know Gansha
