How to calculate the average dice score in binary image segmentation for multiple data? Should I calculate the dice score for each image separately and then average them? or do I need to calculate a single dice score over the total "TP", "FP", and "FN" values for all images? Which one is the correct way?

Thank you for the answer Mr. Acharjya. I found an answer about this that contradicts the reference you shared from another form page. What is your opinion about that?
