作者:

Highlights:

• A new low-rank matrix factorization model is raised by modeling noise with a MoAL.

• The new method AQ-LRMF performs well for various kinds of noise.

• An EM-based efficient algorithm is provided to estimate the parameters in AQ_LRMF.

• Our model AQ-LRMF can automatically learn the weight of outliers.

• AQ-LRMF performs best in capturing local structural information in real images.
