    Patent number: 10847003
    Abstract: An archival video system uses profile images as a background for an image and delta images to indicate the difference between a current image and a profile image. An image may be segmented into multiple sectors, with each sector compared to a profile sector. The resulting image may be constructed using references to previously stored sectors from different images.
