To retain the character information of the smart meter chip image and remove noise interference, a chip image de-noising algorithm combining two-dimensional variational modal decomposition algorithm and non-local mean fil-tering was proposed. On the basis of the center frequency observation method, 2D-VMD was used to decompose the noisy chip image into K modal components, and the noise modal components were removed according to the structural similarity measure (SSIM) threshold method, the NLM algorithm used to the effective component in the 2D-VMD algorithm and through the way of the secondary image denoising to achieve the effect of precise denoising. Experimental results show that the mean square error value and the peak signal-to-noise ratio of proposed algorithm are superior to the traditional filtering algorithms.
