Hi, I have obtained the PDF of an gray scale image.The research paper I am referring to says to fix a threshold such that anything lower than the threshold becomes the foreground and the values above the threshold becomes the background. Based on what should I set my threshold value? Can anybody help me with the matlab code?
Thank You.

That is really hard when we dont know have information about your image. Can you use the function " histogram " and show us the results?
