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!

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);
