I have 200 face images in a folder,I have to select only male faces from it,please help below is my code thanks!!!

clear all;
close all;
clc;
CLASSROOM_FOLDER = 'G:\IMG Class Database\';     % Classroom folder 
FACE_FOLDER      = 'G:\MPI Face Database\';      % Face folder 
COMPOSITE_FOLDER = 'G:\Composite Image DatabaseMale\'; % Output folder
CLASSROOM_FILENAMES = dir(CLASSROOM_FOLDER);       
FACE_FILENAMES = dir(FACE_FOLDER);
CLASSROOM_FILENAMES = CLASSROOM_FILENAMES(3:end);
FACE_FILENAMES = FACE_FILENAMES(3:end);
numClassrooms = size(CLASSROOM_FILENAMES);
numFaces = size(FACE_FILENAMES);
for currentClassroom = 1:numClassrooms
classroomImage = imread([CLASSROOM_FOLDER CLASSROOM_FILENAMES(currentClassroom).name]);  
    for currentFace = 1:numFaces
        faceImage = imread([FACE_FOLDER FACE_FILENAMES(currentFace).name]);
        M_face = size(faceImage,1);
        N_face = size(faceImage,2);
        compositeImage = classroomImage;
        compositeImage((end/2)-(M_face/2):(end/2)+(M_face/2)-1,(end/2)-(N_face/2):(end/2)+(N_face/2)-1,:) = faceImage;
        for i=1:size(classroomImage,1)
            for j=1:size(classroomImage,2)
              if(compositeImage(i,j,1) == 0)
                  compositeImage(i,j,:) = classroomImage(i,j,:);
              end
            end
        end
        % Store composite images to disk
        filename = sprintf('Class%d_Face%d.jpg',currentClassroom, currentFace);
        fullFilename = [COMPOSITE_FOLDER filename];
        disp(fullFilename);  
        imwrite(compositeImage,fullFilename); % Using imwrite to save the image into compositeImage 
    end % currentFace
end % currentClassroom

What kind of help do you want, other than how to format your code: http://www.mathworks.com/matlabcentral/answers/13205#answer_18099

In your question has two parts 1. Call the images and 2. Identify face Male or Female

   % Save all images name in a symmetric manner before doing the operation 
   % names for example im1,im2,im3...
   %Save the folder of images in the current directory
   path_directory='folder_name'; % 'Folder name'
   original_files=dir([path_directory '/*.jpg']); %Note: Image format
   for k=1:length(original_files)
      filename=[path_directory '/' original_files(k).name];
      image_orginal=imread(filename);
      % Convert gray
      % First Part is done
     % Choose only male faces 
     % Write a code for face identification whether male or female
     % For that Image Analyst sir clearly mentioned the link of the website 
     %http://illusionoftheyear.com/2009/05/the-illusion-of-sex/
     % Which mentioned that The Illusion of Sex demonstrates that contrast is an important cue for 
     %perceiving the sex of a face, with greater contrast appearing feminine, and lesser contrast 
     %appearing masculine
     % measure the contrast of the image (very subjective topic)
     % Choose threshold
     % if less than threshold male else female
     % Save if yes male otherwise discard
  end
