Abstract: This paper proposes a tensor model for video rain streaks removal based on total variational regularization and L_2,1 norm to solve rain streaks shielding. Firstly, the prior information of rain streaks component and the video background are preprocessed to obtain the corresponding regularization condition, so as to enhance the sparsity of each part and facilitate the separation of rain streaks. Then, considering the existence of irregular dynamic objects in the video, a total variational regularization term is introduced to suppress the variation of background intensity and alleviate the misjudgment of rain streaks. The alternating direction method of multipliers (ADMM) can be used to effectively solve the proposed tensor model, and carried out a large number of experiments on the synthetic and real datasets. Experimental results show that the proposed method under dynamic background can effectively remove the video rain streaks and retain more background details simultaneously. Compared with other relevant methods, the proposed method has great advantages in three comprehensive quantitative performance measures of peak signal-to-noise ratio (PSNR), structural similarity (SSIM) and residual error (RES).
