Hu, Y., Zhang, D., Ye, J., Li, X., & He, X. (2013). Fast and accurate matrix 
completion via truncated nuclear norm regularization. IEEE Transactions on 
Pattern Analysis and Machine Intelligence, 35(9), 2117-2130.

First written by debingzhang, Zhejiang Universiy, November 2012.

The code contains:
|--------------
|-- TNNR_main.m            entrance to start real image experiment
|-- TNNR_synthetic.m       entrance to start synthetic experiment
|-- function
    |-- PSNR.m             compute the PSNR and Erec for recovered image
    |-- nuclear_norm.m     compute the nuclear norm of matrix
|-- TNNR-admm/             optimization via ADMM
    |-- result/            directory for saving experimental results
    |-- admm_pic.m         optimization via ADMM
    |-- admmAXB.m          iteration to sovle ||X||_*
|-- TNNR-apgl/             optimization via APGL
    |-- result/            directory for saving experimental results
    |-- admm_apgl.m        optimization via APGL
    |-- apglAXB.m          iteration to sovle ||X||_*
                                observed elements; rows with more observed 
                                elements are given smaller weights
|-- mask/                  directory for various mask types, 300x300
|-- pic/                   directory for original images

For algorithm interpretation, please read Hu et al. (2013) paper, in which 
more details are demonstrated.
