Existing solutions are mostly based on special sensor hardware or the spectral signature of living skin. This paper uses commercial electro-optical and infrared (EO/IR) sensors to capture a very short video for low cost and fast liveness detection. The key components of our system include: tiny human body and face detection from long range and low-resolution video, and remote liveness detection based on micro-motion from a short human body and face video. These micro-motions are caused by breathing and heartbeat. A deep learning architecture is designed for remote body and face detection. A novel algorithm is proposed for adaptive sensor and background noise cancellation. An air platform motion compensation algorithm is tested on video data collected on a drone. The key advantages are: low cost, requires very short video, works with many parts of a human body even when skin is not visible, works on any motion caused by eyes, mouth, heartbeat, breathing, or body parts, and works in all lighting conditions. To the author's best knowledge, this is the first work on video micro-motion based liveness detection on a moving platform and from a long standoff range of 100 m. Once a subject is deemed alive, video-based remote heart rate detection is applied to assess the physiological and psychological state of the subject. This is also the first work on outdoor remote heart rate detection from a long standoff range of 100 m. On a public available indoor COHFACE data evaluation, our heart rate estimation algorithm outperforms all published work on the same dataset. 收起
