Thanks for your brilliant work!!! I wanna know the function compute_laplacian equals to cv2.Laplacian() in OpenCV? Looking forward to your reply!!!

Thank you for your kind words.

The cv2.laplacian computes a different function, a kind of edge detector. https://docs.opencv.org/3.4/d5/db5/tutorial_laplace_operator.html
