function [features]=feature_extractor_2d(im2)
%this function zones the input image and extracts features for each zone.
srcFiles = dir('C:\Users\Omm\Desktop\thesis\multicharacterrec\*.png'); % the folder in which ur images exists
for i = 1 : length(srcFiles)
filename = strcat('C:\Users\Omm\Desktop\thesis\multicharacterrec\',srcFiles(i).name);
im = imread(filename);
%selecting the universe of discourse
im2=discourser(im);
end
this function is replacing all the previous images to a new image and taking last one as a input but i want to get the features of all the image one by one please guide me how to do it in matlab?

Also please use fullfile() instead of strcat() to build your names.
projectdir = 'C:\Users\Omm\Desktop\thesis\multicharacterrec';
srcFiles = dir(projectdir, '*.png');
numfiles = length(srcFiles);
outputs = cell(numfiles, 1);
for i = 1 : numfiles
filename = fullfile(projectdir, srcFiles(i).name);
thisimage = imread(filename);
%selecting the universe of discourse
outputs{i} = discourser(thisimage);
end

saved_images = cell(numfiles, 1);

saved_images{i} = thisimage;
