pybrisque about compute score

hi, I just try your code, seems it is inversely proportional to psnr, image with higher pnsr will got lower score, is that right?

Hi @suke27. In BRISQUE, the lower the score, the better the image quality should be. While In PSNR, the higher the score, the more similar the image is to the reference image. It really depends on how you use them (because they are 2 different methods - one is no-reference method and the other is with reference), but if you have distorted images from one reference, yes the higher the PSNR, the lower BRISQUE should be (assuming that the reference has better quality)

@akbargumbira Test Image 1.jpg 2.jpg

Wasn't 2.jpg should be higher score?

It seems that it's a failed case using BRISQUE

Hi, Isn't Brisque score supposed to be between 0 and 100 ? On 500 images, 15 got a score above 100. Is that normal ? Thx

And isn't a good quality image supposed to have a score near 0 ?
