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?

image = imread(filename);
is still using "image" as the name of a variable.

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

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