摘要：Digital watermarking has been proposed as a viable solution to the need of copyright protection and authentication of multimedia data in a networked environment, since it makes possible to identify the author, owner, distributor or authorized consumer of a document. Watermarking payload is a topic in which the watermarking researchers have a great interest at present. In this paper, we estimate the maximum watermarking data hiding capacity or the maximum number of bits that can be embedded in spatial domain images under the constraint of perceptual invisibility in the carriers. We studied the maximum payloads under different intensities and verified its effectiveness through experiments The purpose of the paper, which was to provide a payload reference for watermarking researchers, was achieved by studying the maximum payloads which is related to factors, in addition to the embedding intensity, such as the size of image, image roughness and visual sensitivity.
