System for Use of Complexity of Audio, Image and Video as Perceived by a Human Observer

摘要

A system and method for determining and using complexity of image, audio, or video information as perceived by a human observer is provided. The system and method may determine complexity of the image, audio or video information by using a perceptual model, such as a lossy compression system. The compression system may remove portions of the information (and reduce the size of the information) in ways nearly imperceptible to a human, while preserving the overall human perception. The size of the information after the compression may provide an indicator of the complexity, such as provide an upper bound on the complexity of the information as perceived by a human. The complexity of the information, once determined, may be used in a variety of ways, such as characterizing the information (including fingerprinting the information), comparing the information with other image, audio or video information, or presenting the information.
