Abstract: Recently, code construction approaching the rate-distortion bound of reversible data hiding has been proposed by Lin , in which the coding/decoding process needs the optimal probability distribution of marked-signals as parameters. Therefore, the efficiency and accuracy of estimating the optimal marked-signal distribution will greatly influence the speeds of encoding and decoding. In this paper, we propose a fast algorithm to solve the optimal marked-signal distribution. Furthermore, we modify the method to achieve the optimal distribution directly according to a given distortion constraint or an expected embedding rate, which makes it more practical for applications. © 2005-2012 IEEE.
