Hello,

I have the following code which was provided by one of the members. It reads an image and calculate the surface and sectional areas.

I tried to modify the code so that it reads several images, say from 1-100 and store the sectional and surface areas in a text file, but it didn't work.

Any suggestions?

inpict = rgb2gray(imread('44.png'));
% generate binary image of object alone
m = ~imbinarize(inpict,'adaptive','foregroundpolarity','dark','sensitivity',0.5);
m = bwareafilt(imclearborder(m),1);
st = strel('disk',20);
m = imerode(~bwareafilt(imerode(~m,st),1),st);
%imshow(m)
% calculate areas
d = sum(m,1);
d = d(d~=0);
Asurf = sum(pi*d) % assuming rotational symmetry
Asect = sum(m,'all')
