trackbar_cv

This repository creates a simple parameterized open_cv trackbar for making live updates to an input image.


The trackbar is created with 2 key functions: a callback_function to handle parameter updates, and a function to draw the image

Use the callback_function to compute any changes from a parameter update. What is returned from the callback_function is provided to the draw function.


Note: The python 2.7 code was moved to the python2.7 branch. More documentation to follow

Note: (9/1/2019) Updated example.py to work around apparent opencv 4.0 bug. Image must be uint8.
