Flikcer -- A Chrome Extension to Resolve Online Epileptogenic Visual Content with Real-Time Luminance Frequency Analysis
Jaisal Kothari, Ashay Srivastava

TL;DR
Flikcer is a Chrome extension that detects and modifies epileptogenic visual content in videos in real-time, helping to prevent seizures in photosensitive viewers through luminance frequency analysis.
Contribution
It introduces a real-time, computationally efficient algorithm combining machine learning and computer vision to identify and mitigate seizure triggers in online videos.
Findings
Successfully detects epileptogenic content in real-time
Provides safer video versions for download
Operates efficiently on standard hardware
Abstract
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.
