Wavelet technique recovering image blurred by mixed Gaussian and salt-pepper noise
Junquan Hu, Huang Daren, Wang Zhenwu, Zeyin Zhang · Analysis in Theory and Applications · 2003
In this paper, we propose a new method to removing the mixed Gaussian and salt-pepper noise based on wavelet. To estimate outlier, A scheme called max-min method is adopted after DWT. Experimental results show that this method is more effective than common image restoration methods, such as Median filter, center weighted median filter.
