Flikcer -- A Chrome Extension to Resolve Online Epileptogenic Visual Content with Real-Time Luminance Frequency Analysis
This addresses safety for users with photosensitive epilepsy and general discomfort, though it is incremental as it applies existing methods to a specific domain.
The paper tackled the problem of epileptogenic visual content in online videos by developing Flikcer, a Chrome extension that detects seizure triggers using real-time luminance frequency analysis, resulting in a tool that identifies timestamps and provides safer video versions.
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.
