Abstract :
An arbitrarily rotated image should not be recognized as a different one, but the conventional image perceptual hashing algorithms can only deal with this partially. Different to watermarking, image perceptual hashing does not need to embed information into the image content, this make it possible that perceptual hashing can treat the synchronization problem in a new manner. In this paper, three cyclic coding based perceptual hashing methods are proposed, and the performance under rotation is tested as well as other common attacks. Meanwhile, by dividing the image signal into three perceptual channels, we discuss which one is better for coding with in spatial domain.
