bro, I want to save the eccentricity and metric values of many images so that they form a table of eccentricity values and a metric of multiple images.
How do i make a loop?
source code:
clear; clc; close all;
%mfolder='E:\Kuliah\TesMatlalb\tesLATIH';
%filenames = dir(fullfile(mfolder, '*.png'));
%total = numel(filenames);
i = imread('21.png');
im = im2bw(i,.25);
bw = imcomplement(im);
bw = imfill(bw,'holes');
bw = bwareaopen(bw,50);
%figure,imshow(bw);
[bw,num] = bwlabel(bw);
bbox = zeros(num,4);
RGB4 = i;
for k = 1:num
bw2 = bw==k;
[B,L] = bwboundaries(bw2,'noholes');
stats = regionprops(L,'All');
perimeter = cat(1,stats.Perimeter);
area = cat(1,stats.Area);
eccentricity = cat(1,stats.Eccentricity);
metric = 4*pi*area/perimeter^2;
bbox(k,:) = cat(1,stats.BoundingBox);
end
RGB5 = insertShape(i, 'Rectangle', bbox, 'LineWidth', 1);
figure, imshow(RGB5);

Index your variables with k:
area(k) = cat(1,stats.Area);
eccentricity(k) = cat(1,stats.Eccentricity);
metric(k) = 4*pi*area/perimeter^2;

Thanks, i use this
metric(1,k) = 4*pi*area/perimeter^2;
