Quality Assessment of In-the-Wild Videos

License

Description

VSFA code for the following papers:

Intra-Database Experiments (Training and Evaluating)

Feature extraction

CUDA_VISIBLE_DEVICES=0 python CNNfeatures.py --database=KoNViD-1k --frame_batch_size=64

You need to specify the database and change the corresponding videos_dir.

Quality prediction

CUDA_VISIBLE_DEVICES=0 python VSFA.py --database=KoNViD-1k --exp_id=0

You need to specify the database and exp_id.

Visualization

tensorboard --logdir=logs --port=6006 # in the server (host:port)
ssh -p port -L 6006:localhost:6006 user@host # in your PC. See the visualization in your PC

Reproduced results

We set seeds for the random generators and re-run the experiments on the same ten splits, i.e., the first 10 splits (exp_id=0~9). The results may be still not the same among different version of PyTorch. See randomness@Pytorch Docs

The reproduced overall results are better than the previous results published in the paper. We add learning rate scheduling in the updated code. Better hyper-parameters may be set, if you "look" at the training loss curve and the curves of validation results.

The mean (std) values of the first ten index splits (60%:20%:20% train:val:test)
