This is the official repository for NTIRE2022 Perceptual Image Quality Assessment Challenge Track 2 No-Reference competition. We won first place in the competition and the codes have been released now.

Abstract: No-Reference Image Quality Assessment (NR-IQA) aims to assess the perceptual quality of images in accordance with human subjective perception. Unfortunately, existing NR-IQA methods are far from meeting the needs of predicting accurate quality scores on GAN-based distortion images. To this end, we propose Multi-dimension Attention Network for no-reference Image Quality Assessment (MANIQA) to improve the performance on GAN-based distortion. We firstly extract features via ViT, then to strengthen global and local interactions, we propose the Transposed Attention Block (TAB) and the Scale Swin Transformer Block (SSTB). These two modules apply attention mechanisms across the channel and spatial dimension, respectively. In this multi-dimensional manner, the modules cooperatively increase the interaction among different regions of images globally and locally. Finally, a dual branch structure for patch-weighted quality prediction is applied to predict the final score depending on the weight of each patch's score. Experimental results demonstrate that MANIQA outperforms state-of-the-art methods on four standard datasets (LIVE, TID2013, CSIQ, and KADID-10K) by a large margin. Besides, our method ranked first place in the final testing phase of the NTIRE 2022 Perceptual Image Quality Assessment Challenge Track 2: No-Reference.

Network Architecture

Dataset

The training set is PIPAL22 and the validation dataset is PIPAL21. We have conducted experiments on LIVE, CSIQ, TID2013 and KADID-10K datasets.

NOTE:

• Put the MOS label and the data python files into data folder.
• The validation dataset comes from NTIRE 2021. If you want to reproduce the results on validation or test set for NTIRE 2022 NR-IQA competition, register the competition and upload the submission.zip by following the instruction on the website.

Training

Training MANIQA model:

# Modify train dataset path (PIPAL21 training dataset (PIPAL21 training dataset is same as PIPAL22)): "train_dis_path"
# Modify validation dataset path (PIPAL21 validation dataset): "val_dis_path"

python train_maniqa.py

Inference for PIPAL22 Validing and Testing

Generating the ouput file:

# Modify the path of dataset "test_dis_path"
# Modify the trained model path "model_path"

python inference.py
