Video content with fast luminance variations, or with spatial patterns of high contrast - referred to as epileptogenic visual content - may induce seizures on viewers with photosensitive epilepsy, and even cause discomfort in users not affected by this disease. Flikcer is a web app in the form of a website and chrome extension which aims to resolve epileptic content in videos. It provides the number of possible triggers for a seizure. It also provides the timestamps for these triggers along with a safer version of the video, free to download. The algorithm is written in Python and uses machine learning and computer vision. A key aspect of the algorithm is its computational efficiency, allowing real time implementation for public users.
