Pore size distribution chart
显示 更早的评论
Hello,
I need some assistance here...
I would love to know how do you create a distribution chart based on size and number (amount) of the pores.
Thank you!

Can you show distribution chart you want to see (simple drawing)?

It's about like this but it also depends on the small pore (white pixel).
And on the left bottom side of the picture above, there's some kind of noise or small black pixels on the white pixel pore that may separate the white pore and eventually lead to missinterpretation.

Use regionprops
I = imread('image.jpeg');
I1 = im2bw(I); % binarize image
cc = bwconncomp(I1); % or 'bwlabel' to separate each region
stats = regionprops(cc, 'Area'); % calculate area of each separate region
area = cat(1,stats.Area);
area(area>500) = []; % filter bigger blobs/regions
hist(area,20) % histogram of 20 groups
xlabel('size')
ylabel('number')
result

Sorry, forgot this line
area = cat(1,stats.Area);
I correct the code. Look
