'''
This program demonstrates Laplace point/edge detection using
OpenCV function Laplacian()
It captures from the camera of your choice: 0, 1, ... default 0
Usage:
python laplace.py <ddepth> <smoothType> <sigma>
If no arguments given default arguments will be used.
Keyboard Shortcuts:
Press space bar to exit the program.
