how to calculate area, perimeter and circularity of objects in an image using regionprops

20 views (last 30 days)
I tried this code for the image, it runs smoothly but doesn't show results.I want to calculate the area, perimeter and circularity for each object in this image and show results in the end. Kindly help me with this and please mention where the problem exists.
B = bwlabel(img9);
stats = regionprops(B,'Area', 'Perimeter');
allAreas = [stats.Area];
allPerimeters = [stats.Perimeter];
circularities = (4 * pi * allAreas) ./ allPerimeters .^2;
stats = regionprops('table',img9, 'Area', 'Perimeter');
