PyTorch 1.3 implementation of the following paper:Kang L, Ye P, Li Y, et al. Convolutional neural networks for no-reference image quality assessment[C]//Proceedings of the IEEE Conference on Computer Vision and Pattern Recognition. 2014: 1733-1740.

• The optimizer is chosen as Adam here, instead of the SGD with momentum in the paper.
• the mat files in data/ are the information extracted from the datasets and the index information about the train/val/test split. The subjective scores of LIVE is from therealigned data.

CUDA_VISIBLE_DEVICES=0 python main.py --exp_id=0 --database=LIVE

Before training, theim_dir inconfig.yaml must to be specified.Train/Val/Test split ratio in intra-database experiments can be set inconfig.yaml (default is 0.6/0.2/0.2).

Test Demo

python test_cross_dataset.py --help

TODO: add metrics calculation. SROCC, KROCC can be easily get. PLCC, RMSE, MAE, OR should be calculated after a non-linear fitting since the quality score ranges are not the same across different IQA datasets.
