In this paper, a novel spatial domain sigma-delta modulator using discrete-time cellular neural networks (DT-CNNs) is proposed.
Since the nature of CNN dynamics with the output function which has two saturation regions is to binarize the input image,
CNNs have a capabilities as a spatial domain sigma-delta modulator. In the proposed architecture, the A-template is used for a digital to
analogue converter (DAC), the C-template works as an integrator, and the nonlinear output function is for the bilevel output.
Moreover, the dynamics is designed for obtaining an optimal reconstruction image.
The experimental results show a good reconstruction performance and capabilities of CNN as a sigma-delta modulator. |
