For the low-rank matrix and tensor minimization problem, the optimal solution of convex function can be obtained easily, and the better low-rank solution can be obtained from the local minimum of the corresponding nonconvex function. The low-rank tensor recovery problem based on the nonconvex function is studied in this paper. A nonconvex low-rank tensor model based on lp norm is proposed. In addition, tensor based iteratively reweighted nuclear norm algorithm is proposed to solve the nonconvex low-rank tensor minimization problem. The weighted singular value thresholding problem is solved by the tensor based iteratively reweighted nuclear norm algorithm. The objective function value monotonically decreases and its convergence can be theoretically proved. The recovery performance of the proposed method is demonstrated by comprehensive experiments on both synthetic data and real images.
