Project description
Replay is a video review board for the VAST Builders Challenge. A person picks a camera, watches the replay with person boxes and a scene caption, and asks for a specific violation. The page keeps the clip that matches and states the rule that applies. This stack was proven on our own recorded clips. During the hackathon, we had team members perform a variety of violations - such as trespassing areas, and touching the fire alarm. Our solution helps finds these violations with predefined rules, and also allows additional rules to be defined via natural language. Clips were hybrid indexed and retrieved using VAST Data. Cursor was used to do development. Coreweave was used to host the Nvidia Cosmos reasoning used for captioning clips.
