Hi! I am quite new to OpenCV, image quality assessment, machine learning etc.  
I have a task to analyze which image has better quality comparing 2 images.  
Currently I want to implement it using Reduced-reference or No-reference method. I am curious if that is possible to do using C# and OpenCVSharp.  
I found some information about it is possible using BRISQUE , but I could not find any pre trained model which will suit for that task.  
Maybe anyone knows if there is any pre trained BRISQUE model , tutorial on how to train model using OpenCvSharp or any other way how it can be done using c#?  
Best regards
