WANG Heng, SANG Rui-juan, ZHANG Hua, et al. A new image denoising method for monitoring in intense radioactive environment[J]. 2011, 30(11): 59-61. DOI: 10.13873/j.1000-97872011.11.031.
Image or video monitoring in intense radioactive environment is the foundation of remote operation of engineering in high risk environment.By the influence of energetic
the signal noise ratio(SNR)of image by direct accessing is very low.According to the characteristics of the noise.A composite image denoising method of processing is proposed
which combines adaptive median filter and wavelet transform of automatic threshold.In the algorithm analysis
the noise images is chosen by influence of γ-rays
which are collected when dealing with the source of one irradiation plant.Analysis shows that the proposed method has significant effect in reducing and keeping the edge of image
and it can meet the needs of monitoring of image in different radiation environment.
