MATLAB: Automatic intake of the input ( tartget images) from matlab directory in Target Detection

automatic target detection

hi, i am writing a program for target detection in matlab. In this i'll be manually entering the original image using input()command, then i want the program to take input of target image automatically i.e take each image one by one in my current matlab directory and do target detection i.e follow the program,and then tell that which target image is detected in the original image. basically i want some changes in lines marked by start of wrd help… in the code written below (this code is not created by me). please help..
% Target Recongition
% Part(1) : Entering the image for MATLAB
fprintf('\n This program detects a target in an image')
fprintf('\n Entering the image for MATLAB…')
fprintf('\n Save the image or its copy in MATLAB working Directory')
imagname = input('\n Enter the name of the imagel filename.ext) : ','s');
w = imread(imagname);
w = im2double(w);
sizw = size(w);
figure
imshow(w)
title('Input Image')
pause(3.5);
close;

Best Answer

Something like ...
temp = dir;
filenames = {temp(3:end).name}; % The first two names are . and .. and should be ignored
for ifile = 1:length(filenames)
   % your code
end
If there are other files in the directory you could use dir('*.jpg') or whatever your image type is ...
