In-service Insulator Image Denoising
A Poisson-Gaussian(PG)denoising method for inservice insulator image is proposed.The existing spatial-based method can avoid the preserve more detail information than the transform-based method.Various transforms have been used for image denoising.However,the transforms have disadvantages such as aliasing and lack of directional selectivity.Meanwhile,the conventional redundant transform-based image denoising approaches require more memory and consume more time.In order to capture detail information of images more efficiently,and reduce the computation cost,we propose a hybrid method to improve quality of denoised insulator image in dual domain.Experimental results show that the proposed method is able to significantly improve the PG denoising performance in visual inspection.
