Hi Joshua,
I tried to use chipQA to train and test its performance on a CSIQ-VQA database, which is a 480p resolution database.
1 - I run chipqa_yuv.py get the feature file
2 - I run python cleaner_svr.py --score_file /path/to/score.csv --feature_folder feature_folder --train_and_test
I got the all_pred = [33.22243675 49.20781647 50.0144947 41.65980157 41.57749611 40.87659356, 61.43243688 58.08024139 38.79844636 58.73480296 46.18201971 36.00328378, 36.96726173 42.92148637 53.04071207 63.78199282 53.71268326 31.00923555, 43.38495816 44.25350569 43.77634616 44.97062795 44.97958702 44.92278459, 49.21896745 50.34141739 48.01144443 50.7113197 53.70022118 53.09089083, 36.81422243 42.11125906 47.5120631 48.23488525 52.38174794 59.13939887, 43.95188126 40.72350856 39.07306079 39.36255459 38.9502675 37.87678828, 36.04681885 38.40384619 41.65701426 40.27273715 42.31758531 43.51008817, 33.85725812 39.69753213 48.37801187 43.89804409 44.25391719 44.2835234 ]

I would get "lib\site-packages\scipy\optimize\minpack.py:834: OptimizeWarning: Covariance of the parameters could not be estimated
category=OptimizeWarning)" several times during this step. And the results of PLCC and SROCC only (0.33308124176152726, 0.3385172479512102).
Can you tell me how to solve this problem and get the right result.
Thanks in advance,
Hugh
Hi,
I try to use ChipQA to evaluate the quality of a sequence and I failed. Can you tell me what is wrong in my following steps:
1 - I get a "feature" file after the command
python.exe chipqa_yuv.py --input_file file.yuv --results_file .\result --width 1920 --height 1080 --bit_depth 8 --color_space BT709
2 - I run
python zip_feat_and_scores.py chipqa_apv_features apv_livestream_scores.csv ai
3 - I run
python svr.py ai
4 - I run
python testing.py result.
Last step failed with the error "FileNotFoundError: [Errno 2] No such file or directory: 'LIVE_Livestream_trained_svr.z'"
When I check the code, to produce 'LIVE_Livestream_trained_svr.z', I need to run svr.py with the variable dataset to "onlytrain". But if I apply this change I have another error.
Can you tell me how I can use your software to evaluate my YUV sequence ?
Thanks in advance,
Adrien
