Abstract
A system for lossless compression of high frame rate imagery includes at least one non-transitory computer readable storage medium having instructions encoded thereon that, when executed by at least one processor, implement operations to compress high frame rate imagery in a lossless manner, the at least one non-transitory computer readable storage medium including: logic to encode frame deltas to decrease pixel dynamic range; logic to localize frame deltas; and logic to encode subframes with lookback history to further decrease pixel dynamic range for temporary obstructions.
