Filter Feedback: Automated QA

Finding configurations for Filter Feedback that produce interesting results is time-consuming because generally only a tiny fraction of all randomly generated variants ends up being visually pleasing. Common problems are:

• Configurations are too unstable; they descend into infinity (resulting in a completely black or white screen) too fast
• Results contain strobe-like flickering, oscillating between inverted states
• There is too little movement overall

This tool continuously generates random configurations, renders videos of them, and then judges them by analysing the frames of the video with respect to the problems outlined above. If one or more problems are detected, the configuration gets rejected.

Any configuration that was not automatically rejected that way is then presented to the user for further inspection of the video and additional data.
