Paper Abstract

In this paper, we present an approach of real-time implementation of multimedia data security based on virtual-optics with the aid of a parallel digital signal processor (DSP). In order to partially compensate the parallelism of optical processing lost by digital implementation, we make full use of parallel hardware architecture and parallel computation structure of the TMS320C6701 DSP, leading to a high-efficiency operation. This approach makes it possible for the virtual-optics imaging methodology (VOIM) to be realized in real-time applications in embedded systems for multimedia data security. Experiments with multimedia data are performed to validate the proposed method, and parameter-sensitivities are quantitatively analyzed and illustrated.
