ChipQA-0 is a prototype version of ChipQA. You can read ChipQA-0 here: https://ieeexplore.ieee.org/abstract/document/9287151.

This repository contains code for ChipQA-0. Code for ChipQA will be released in September 2022.

See requirements.txt

To extract features, run

python3 chipqa0.py path/to/input_folder path/to/output_folder

input_folder must contain the videos from which chipqa features will be extracted. output_folder will contain the features that are written out.

After extracting the features, run

python3 zip_feats_and_scores.py input_folder csv_file output_file 

Here input_folder must contain the features generated from the previous step, csv_file must be a csv file with LIVE-APV database names and scores, and output_file will be where the combined features and scores will be stored.

After this, run

python3 svr.py input_file output_folder

to evaluate. input_file must be the path where the zipped features and scores are saved. The predictions and the ground truth MOS for each of the runs will be stored in output_folder.

all_srocc.m can then be used to find the SROCC and LCC.
