Is there a 'fitpiqe' to build the customer Perception-based image quality evaluator model for PIQE?

I found the fitbrisque and fitniqe to build the customer evaluation model for BRISQUE and NIQE. However, I cannot find the fitpiqe to create the Perception-based image quality evaluator for PIQE. Do you know whether there is one, and how to build one?

Thank you.

Hi John,

I do not see "fitpiqe" function in the MathWorks documentation.

However, I understand from the MathWorks documentation that "piqe" function calculates the no-reference image quality score for image using a perception based image quality evaluator and not a default model.

If you need to create a custom evaluator similar to "piqe" that requires training on your dataset, you would need to develop your own implementation. This would depend on your image quality assessment algorithm. You might find it useful to look into machine learning functions in MATLAB, such as those in the "Statistics and Machine Learning Toolbox", which can help you with model training and evaluation.

Please refer to the following MathWorks documentation for more information on:

• "Statistics and Machine Learning Toolbox" - https://www.mathworks.com/help/stats/index.html
• "piqe" - https://www.mathworks.com/help/images/ref/piqe.html

It would be nice for Mathworks to create a fitpiqe for PIQE, just like fitbrisque and fitniqe for BRISQUE and NIQE.
