Visual attention model is a hotspot in the field of multimedia understanding. It is quite helpful for multimedia processing especially in the case that the human vision should be considered. In this paper, a novel information hiding algorithm based on Stentiford visual attention model is proposed. By embedding less information in sensitive region, the invisibility of image with hidden information...
This paper presents a parameter identification method of nonlinear Hammerstein model with two-segment piecewise nonlinearities. Its basic idea is that: First of all, expressing the output of the Hammerstein nonlinear models as a regressive equation in all parameters based on the key term separation principle and separating key term from linear block and nonlinear block. Then, the unknown true outputs...
