I have an image that looks like the one attached and i am trying to smooth its intensity from left to right. I tried the method using the imtophat filter but it did not give me good results because there is not a lot of background in the image. I want to fit the background to a linear f(x) function and then correct it.
1. Does anyone know how to fit the background to a linear function?
2. Once you have the background function, how do you correct the data?

Hi Angela
One thing that you could try is to use 'imadjust' to improve the visibility of the image after top-hat filtering. If this doesn't work, try using the 'lazysnapping' or 'grabcut' function to segment the image into foreground and background. Once you filter out the area of interest in the image, you may get better results.
Cheers
