Dear all;
I want to collect all same value coins in each figure. For example, all 1 cent coin in 1 figure, all 5 cent coin in 1 figure. How can I do that?
Really appreciate for your help
clc;
close all;
clear;
I = imread("money.png");
Ig = rgb2gray(I);
imshow(Ig);
Ib = imbinarize(Ig,'global');
imshow(Ib);
se = strel('disk',2);
Ih = imerode(Ib,se);
Ih = Ib - Ih;
imshow (Ih);
If = imfill(Ih,'holes');
label = bwlabel(If);
max(max(label));
im1 = (label ==1);
figure;
imshow(im1)
for i = 1:max(max(label));
[row, col] = find(label ==i);
len = max(row)-min(row)+2;
breath = max(col)-min(col) +2;
target = uint8(zeros([len breath]));
sy = min(col) - 1;
sx = min(row) - 1;
for j = 1:size(row,1);
x = row(j,1) - sx;
y = col(j,1) - sy;
target(x,y) = I(row(j,1),col(j,1));
end
mytitle = strcat('Object Number:',num2str(j));
figure;
imshow(target);
end

It's a generic, general purpose demo of how to threshold an image to find blobs, and then measure things about the blobs, and extract certain blobs based on their areas or diameters, like dimes or nickels only.
