我们提出了一种粒子模型,用于通过随机共振研究光学噪声图像恢复。将在非线性介质中传播的光视为运动粒子,用于分析信号和噪声的非线性耦合。由于非线性,信号有可能以牺牲噪声为代价来增强自身。施加的电场、噪声强度和相关长度是影响恢复效果的重要参数。成功恢复了信噪比为 的噪声隐藏图像,理论上得到了最佳互相关增益为 6.1。
We propose a particle model for investigating the optical noisy image recovery via stochastic resonance. The light propagating in nonlinear media is regarded as moving particles, which are used for analyzing the nonlinear coupling of signal and noise. Owing to nonlinearity, a signal seeds a potential to reinforce itself at the expense of noise. The applied electric field, noise intensity, and correlation length are important parameters that influence the recovery effects. The noise-hidden image with the signal-to-noise intensity ratio of is successfully restored and an optimal cross-correlation gain of 6.1 is theoretically obtained.
