| 摘 要： | SF6断路器是电力系统中常见的电气设备,针对SF6断路器气体泄漏红外图像中广泛存在的激光散斑噪声,提出一种抑制散斑噪声的新算法.将同态均值滤波与小波变换结合,并应用贝叶斯软阈值,对红外图像进行去噪处理.研究中,将该算法与同态均值滤波、同态均值滤波与传统周定小波阈值结合滤波等算法作了比较,结果表明,在图像标准偏差、信噪比和散斑指数等常用性能指标上所提算法优于其他算法. |

| Abstract: | SF6 switcher is a common electrical device in power system.Aiming at the laser speckle noise existing widely in the gas leakage infrared image of SF6 switcher,an image de-noising method is proposed in this paper.Homomorphic mean filter,wavelet transform and Bayesian soft threshold are adopted to de-noise the infrared image.In the study,the proposed algorithm is compared with homomorphic mean filter and homomorphic mean filter combined with traditional wavelet threshold denoising algorithm.Experimental resul... |
