A New Impulse Noise Image Recovering Method
Hui Liu · Journal of Jilin University(Science Edition) · 2008
In order to denoise impulse noises in images,an adaptive window switching median filtering method is proposed in this paper.First, each pixel is classified as signal or noisy point by the BP-net.Next,the image is filtered by an improved median filter.According to the result of noise detection,the filter can adjust adaptively window's width and sample choicely,each noisy point in image is denoised by filtering.In terms of suppressing impulse noise and preserving image details,the proposed method is better than that based on median filter.Even in the extreme case of 70% noise corruption,noisy images can be effectively recovered.
