        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?

在 MATLAB Online 中打开

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
