Image detection.

[ThNera]

I would like to know if there is any way you can use python in order to detect images in a live game that you play. For example, detecting head/players images in the game.

This is an image processing / computer vision task, which can be done in Python, as well as numerous other languages.
You need to make sure though that you can capture the screen and process the image with a high enough frequency for your needs.
