This is the source code for the CVPR'20 paper "Blindly Assess Image Quality in the Wild Guided by A Self-Adaptive Hyper Network".

• Python 3.6+
• PyTorch 0.4+
• TorchVision
• scipy

(optional for loading specific IQA Datasets)

• csv (KonIQ-10k Dataset)
• openpyxl (BID Dataset)

Predicting image quality with our model trained on the Koniq-10k Dataset.

To run the demo, please download the pre-trained model at Google drive or Baidu cloud (password: 1ty8), put it in 'pretrained' folder, then run:

python demo.py

You will get a quality score ranging from 0-100, and a higher value indicates better image quality.

Training and testing our model on the LIVE Challenge Dataset.

python train_test_IQA.py

Some available options:

• --dataset: Training and testing dataset, support datasets: livec | koniq-10k | bid | live | csiq | tid2013.
• --train_patch_num: Sampled image patch number per training image.
• --test_patch_num: Sampled image patch number per testing image.
• --batch_size: Batch size.

When training or testing on CSIQ dataset, please put 'csiq_label.txt' in your own CSIQ folder.
