We have segmented a part from grey scale image using image segmenter (app in mat lab
) and stored as matlab structure. from that structure , how can we calculate the area of the segmented part related to the original image size.
You can try obtaining the convex hull of the segmented image from which
you can estimate the area assuming it is calibrated. Also why not convert to
binary image and just do a summation of the image matrix.
Good Luck
Cheers
