Abstract :
The paper presents an efficient hardware realization of circular back propagation (CBP) networks on digital signal processors (DSP). The resulting neural-system is aimed at enhancing "smart" TV displays and supports the estimation of perceptual quality of visual signals. The DSP-based neuro-platform operates on raw digital signals and yields the associate estimate of perceived quality in real time. Experimental results confirm both evaluation accuracy and timing performance.
