Abstract: Highlights•We propose a new low-rank minimization model and utilize it to solve color image denoising problem.•We design an efficient and accurate optimization algorithm to solve the proposed model based on the ADMM framework.•We provide a theoretical guarantee to show that the sequence generated by our algorithm converges to a critical point.•Extensive experiments demonstrate the superiority of the proposed model.
