Robust principal component analysis(RPCA)is a very effective method to recover both the low-rank and sparse components.This paper extends RPCA to the case of tensor and proposes a framework of multilinear robust principal component analysis(MRPCA).First
it establishes the model of MRPCA which minimizes a weighted combination of the tensor nuclear norm and

norm.Then
it employs the augmented Lagrange multipliers algorithm to solve the above nuclear norm optimization problem.Experimental results demonstrate that MRPCA is more robust than RPCA for the data with multilinear structure.
