  • Patent number: 10769915
    Abstract: A privacy reserving camera including a frame buffer, an object detection and tracking module, an object identification module, an instance segmentation module and an object removal and inpainting module. The frame buffer stores frames of a video stream captured by the privacy preserving camera. The object detection and tracking module detects a moving object in the video stream.
