The complete CODIF metric includes two parts: 1. HED model, 2. CODIF Codes.
Running the HED model to detect the color image, and obtaining the corresponding object contour map, then saving it in the corresponding folder, e.g. test_image\HED_images; HED model download address: https://github.com/senliuy/Keras_HED_with_model
In CODIF Codes, we provided the SVR model trained on the MCL_3D database, and you can run Demo_test.m to directly predict the quality of the synthesized image from the color and depth images；
If you need to retrain in other database, you can modify the code in CODIF Codes for feature extraction, and then use the SVR model for retraining.
