摘要
Abstract
In order to remove the white noise of infrared image effectively and improve the accuracy of infrared diagnosis of electrical equipment,a hybrid Fourier-wavelet de-noising method is used to process the infrared image of porcelain bushing cable terminal in this paper.The main steps of the proposed method are as follows:the noisy image is firstly processed in the Fourier domain by using the Wiener filter,and then,the wavelet coefficients are de-noised in wavelet domain by using the Gaussians scale mixtures (GSM) model which considers the statistical properties of wavelet coefficients,finally,the processed wavelet coefficients are used to reconstruct the model and get the final de-noising image.Simulation results indicate that the infrared image de-noising effect can be effectively improved by using the proposed method in this paper.关键词
