The complex leaf image background is first removed to get a clear leaf sample before further processing. So l using here background elimination mathod. Algorithm is, step1)Manually select ROI in I and store it in R. Step2)generate binary mask. Step3)set J to I. Step4)for each pixel (m,n)in I . Step5) if pixel(m,n) is in R. Step6) set J(m,n) to 1. Step7) else Step8)Set J(m,n) to 0. Step9)compute complement J'. Step10)set I to I+J'. Step11)Crop I to eliminate unwanted image parts. Please send me it's Matlab code using given image.
