    摘要: Methods, apparatuses, and computer program products for image compression are provided. Embodiments include: examining, by an image controller, contextual data of a plurality of uncompressed images; selecting from the plurality of uncompressed images, by the image controller, a group of uncompressed images that have related contextual data; designating, by the image controller, one of the selected images to be a reference image; creating, by the image controller, delta images, each delta image representing differences between the reference image and one of the uncompressed images; and compressing and storing, by the image controller, the reference image and each of the delta images.
