I want to do regression on one image taking other image as reference. I want to match these image DN values using regression.

Tanya — What is a ‘9 polynomial fir’? To me it implies a 9th-order finite impulse response filter. If it’s a 9th-degree polynomial you are fitting with polyfit, why?

How could be solved this problem ?

It can't. Notice she never answered questions about what exactly that means. So, since no one has any idea of what she wants, we can't solve it for her. If you want to start a new question and explain it A LOT better than what Tanya did, you'll probably get an answer.

Thank you for your answer. My question is the following: i have a bunch of templates (let's say 180) and one input image. Like in a puzzle, i need to sum up some of the templates to recompose my input image. I was thinking to apply a linear regression ( non negative one, because i can not use negative weights), and after getting rid of the remaining weights that are associated with really high correlated templates. Are there a better way to do this?
