Abstract
To effectively detect random-valued impulse noise and remove its interference on the image,this paper proposes a new switching total variation denoising method.The method detects and modifies noise in different window neighborhoods of 3 px×3 px,5 px×5 px and 7 px×7 px according to different densities of random-valued impulse noise,and adopts a total variation based method to denoise the pixels that are finally judged as noise.In addition,the method uses a dynamic threshold to perform multiple noise detection and re-moval on the denoised image,thereby further improving the denoising effect.Simulation results show that the method can effectively remove noise and protect image details for images with random-valued impulse noise of different densities.It outperforms other methods in terms of peak signal noise ratio.关键词
