Requirements

• Python 2.7
• Keras 2.1.2
• Tensorflow-gpu 1.3.0

Getting Started

Installation

• Clone this repo:

git clone https://github.com/ysyscool/SGDNet
cd SGDNet
mv SGDNet/acmmm_release/ SGDNet/
mkdir ../checkpoint/

• Download weights from Google Drive. Put the weights into

cd ../checkpoint/

Train/Test

1. Download the IQA datasets. Their saliency maps, used in our experiments, can be downloaded in this link.
2. Modify the paths in config.yaml And then using the following command to train the model (use knoiq10k and DINet as example)

 CUDA_VISIBLE_DEVICES=0 python main.py  --database=Koniq10k --lr=1e-4 --batch_size=19 --out2dim=1024  --saliency=output --phase=train

For testing, modify the variables of arg (in line 276) as the trained checkpoint name in the main.py. And then using the following command to test the model

CUDA_VISIBLE_DEVICES=0 python main.py  --database=Koniq10k --out2dim=1024 --saliency=output --phase=test
