% I have to import images from 40 classes (directories) and each directory
% has 7 images which is i called as subjects. then i need to make a vector
% form of each image and then save it into linear array.
% note my pictures is in grayscale which i will need to be in a linear
% array.
% Below I have written the code but it is giving me following error
%??? Error using ==> imread at 374
%File "d:/ahsan/biometrics/imagedatabase/ATT/s1/1.PGM" does not exist.
%Error in ==> Pr4 at 15
%filename = imread(
%sprintf('d:/ahsan/biometrics/imagedatabase/ATT/s%d/%d.PGM',i,k));
%start program
clc
clear all ;
class = 40 ; % We have 40 folders in our main directory.
subjects = 7; % we have 7 images in our single directory.
for i = 1:class % this loop traverse all directories
for k = 1:subjects % this loop traverse images in single directory
filename = imread( sprintf('d:/ahsan/biometrics/imagedatabase/ATT/s%d/%d.PGM',i,k));
image = importdata (filename, '.PGM');
Y = ones(1,10); %Column array
Y1 = filename;
Y1= reshape(myfilename,1,[]);
Y=Y1;
end
end
%end program
