Pax 📸

Detects and removes camera flashes from a video stream


The aim in developing this module was to use machine vision to detect and eliminate sudden contrast changes, caused mainly by camera speed light. Video footage containing fast flickering images, such as camera flashes is non-accessible for some people with photosensitive epilepsy. It also generally decreases the viewing quality of clips.

This project is a proof of concept, and as such it is yet optimised for production.
It was built at StartHack 19 by myself and Ollie, and won first place :)
