eigen Video Understanding

Aiming to achieve near-human video understanding, in this project we analyze several gigabytes of spatiotemporal data to perform action recognition, multi-person tracking, object permanence and video reasoning. eigen has built a scalable video-understanding platform for long-form video reasoning that scales to new environments and camera angles without any re-training.

eigen also provides a system platform. Running both on the cloud (AWS) and on-prem, it can scale up to thousands of streams into it for cloud-based AI processing. Our AI video algorithms provide efficient streaming and inference. eigen has a web frontend and support for iOS/Android playback. eigen has been tested in several retail POCs serving 200+ streams; its behavioral analytics have also been evaluated through various NEC customers. Using mixed precision and TensorRT, eigen is extremely efficient and incurs very low cloud costs.
