Stochastic resonance (SR) is getting more and more attention in recent few years, as a tool when using noise to enhance system performance. This paper applies SR in the image quantization and presents two types of SR Analog-to-Digital Converter (SR-ADC). One is conventional array SR structured, and another is more efficient by definition of transformation function. It is discovered in the image quantization that the resulting image of SR-ADC has a special visual impression. The image-enhancing performance of SR-ADC is also analyzed. And the low signal-to-noise ratio (SNR) image is enhanced effectively in non-Gaussian noises.
