基于参数调节随机共振的图像去噪研究

Image Denoising method Based on Parameter Adjustment Stochastic Resonance

提出一种图像的参数调节随机共振去噪方法,对来自于同一噪声源的多张同一图像进行处理,将若干张图片中相同位置的元素按列排序处理成周期信号输入双稳态系统,利用参数调节随机共振提高了图像信噪比。实验证明,该方法能显著提高图像质量。

An image denoising method is presented based on parameters adjustment stochastic resonance in this paper. For multiple copies of the same image noised by the same source, the pixel values on the same position are extracted and processed into a periodic signal. We input the signal into a bistable system and the SNR is improved by parameter adjustment stochastic resonance. The experiment results show that this method can significantly improve the image quality of output.
