Hi everyone.
I just want to ask what means mean prediction in a image, to improve the quality of its. I tried to found some information on internet, but I'm not sure of what to do.
From wikipedia, I understand the Mean-Prediction in a JPEG image is the value of 2 blocks + the variance of the block. The problem is i dont understand what I need to do for improve the quality of a JPEG image.
Is more a theorical question, but I really need help to understand what to do when a compression value affects the quality of a original image, and how to applie it. Is there a function on OPENCV that could help me?
Thank you.
