Hi, i have images sets (1.png, 2.png, 3.png....) and load each image for some image detection action through a loop . If detection of img(j) is not possible then save the image name among each other in a new variable: problem_images. Look for this the else section below. The problem_images should look like this. Thank You

...
clear all; close all;
%path/directory of images
currentpath=pwd;
org=strcat(pwd);
edge=strcat(pwd,'\detection');
cd(org);
images=dir('*.png');
N=length(images);
%doing detection stuff for all images in this folder
for i=1:N
[filepath,name,ext] = fileparts(images(i).name);
img = imread(images(i).name);
if size_lines>2
%if image is ok, do some detection stuff...
else
%detection is not possible, save the name of the image(i) in a new variable
problem_images(:,1)=(images(i).name);
end
end

Here, I answered based on decription of the questions
j=1;
for i=1:total_images
%Images call one by one
%Detection Part
result=....% This variable is result from detection
%Store all those image numbers (problem Images) in cell array
if isempty(result);
problem_images{j}=['Image_number',num2str(i)];
j=j+1;
end
end
