imshow(obj)

%%Remove Noise

%%Remove any blobs on the border of the image

%%Remove blobs that are smaller than 7 pixels across
se = strel('disk',7);

%% Measure Object Diameter
diameter = regionprops(open,'MajorAxisLength');
%%Show result
figure(3)
imshow(obj)
d = imdistline; %%Include a line to physically measure the ball
so this in this code, i am able to find pixel diameters of the images which have one circle or one square in them but when i try to use images with two shapes in them, such as a venn diagram or just three random shapes in the image, i get this "Index in position 3 exceeds array bounds (must not exceed 1)"
please help asap
