## Color detection of players (color-detection)

The run script will produce a CSV with the RGB values and percentage of each color.

ToDo:  Classify each color result into two groups, identify hopefully each team by color.

## Players tracking

See article on [players tracking solutions](https://github.com/stephanj/basketballVideoAnalysis/wiki/Tracking-Players)

See also [YouTube](https://www.youtube.com/watch?v=6b__GMsoW4k) video with different solutions.

Required so we can classify the game play action of players.

## Homography mapping of court

Maps the 3D court onto a 2D version, required for analysis of movement.
