Some of the Sample Code

Python
You can look, once compilation is done, in /opencv-master/samples/python/ for many files that can be altered and expressed differently.
#!/usr/bin/env python3

'''
This sample demonstrates Canny edge detection.

Usage:
  edge.py [<video source>]

  Trackbars control edge thresholds.
