Traffic flow computer vision app

Hello everyone! I’ve recently made an app that you can use to count and track the number of vehicles in the road from a video file. The app is primarily powered by the YOLOv3 object detection algorithm for detecting vehicles, and a custom algorithm I’ve made to track vehicle trajectories across frames. I’ve also implemented here a custom slider which gets disabled when the start button gets pressed.

In the future, I plan to include other metrics that can be measured like traffic density, speed, and vehicle distribution. Let me know if you have any suggestions to improve the app!

P.S. If you ever get the chance to use it, I apologize in advance for the really loooow FPS. Heroku isn’t really suited for very taxing processes.
