Measuring glue area with MatLab

See presentation (measuring glue area.pdf) in SLAC ITk meeting on 10/6/20 (https://indico.cern.ch/event/960662/). Commands used in recent studies are on page 8:

im = imread("Image/cropped.png");

imshow(im);

h = imdistline;
gs = rgb2gray(im);
inv = imcomplement(gs);

a = inv >100;
cc = bwconncomp(a);
st = regionprops(cc);

<sort st in descending order in Area>

centroid = cat(1,st.Centroid); hold on;

imshow(a);

plot(centroid(1:1,1),centroid(1:1,2),'b*');

plot(centroid(2:2,1),centroid(2:2,2),'b>');

plot(centroid(3:3,1),centroid(3:3,2),'b<');

hold off;
