Hi,
I know my question may sound confusing, but I am facing with lack of the time.
I have MRI images of many patients that the intensity varies from patient to patient. I know that in some works they are applying histogram equalization and gamma correction, but guessing a correct value for the parameters of these functions is not straight forward. I did not have any choice except post my question here to get some expert advice.
My question is what kind of preprocessing I can apply on these MRIs that improves the processing and results? The following shows one slice: (The aim is to segment cartilage in MRIs)
or like this:
I am a beginner and do not know what kind of filters I can apply.
The other thing is that how can I find a proper parameter for functions. For example, I want to make the cartilage tissue to be appeared better than before, or I do not want to process muscles, so I want to their intensity to be decreased. How can I find optimal gamma value, for example, if I am using gamma correction?
I really appreciate your help.
