Hey people,

I need a help, because I don't know how to extricate myself from a code. My code has to compare two binary images. Image 1 has just some pixels with value 0 and that is also case for Image 2. So, task of my code is to compare if those pixels are overlapped, and if so, overlapped pixels on Image 2 would get a value 1. It has do a recursion for a set of binary images.

I give you my unfinished code, but there are some written comments what it needs to do at those lines.

myFolderInput = 'F:\input_with_flakes\';
myFolderOutput= 'F:\output_wihout_flakes\';
    if ~isdir(myFolderInput)
      errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolderInput);
      uiwait(warndlg(errorMessage));
      return;
    end
    if ~isdir(myFolderOutput)
      errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolderOutput);
      uiwait(warndlg(errorMessage));
      return;
    end
    filePattern = fullfile(myFolderInput, '*.jpg');
    jpegFiles = dir(filePattern);
    for k = 1:length(jpegFiles)
      baseFileName = jpegFiles(k).name;
      fullFileName = fullfile(myFolderInput, baseFileName);
      fprintf(1, 'Now reading %s\n', fullFileName);
      imageArray = imread(fullFileName);
      [i j]=size(imageArray)
      if k==1
          fprintf('The first one is skipped\n')
      else
          for m=1:i
            for n=1:j
                if imageArray(m,n)==imageArray(m,n)  % if Previous Image(m,n)==Current Image(m,n)
                   imageArray(m,n)=1;                % Current Image(m,n)=1;
                elseif imageArray(m,n)==0            % elseif Current Image(m,n)==0
                   imageArray(m,n)=0;                % Current Image(m,n)=0;
                end
            end
          end
      end
      filename = sprintf('Excluded_%s', baseFileName);
      imwrite(imageArray,[myFolderOutput, filename],'jpeg');
    end

Hello,

first of all, in my view at least, I see some logical problems. You have to load the second image(I did not work with images); the comparison "imageArray(m,n)==imageArray(m,n)" will always be true. Second thing I noticed is that if your "imageArray(m,n)==0", you will have a 1 because "imageArray(m,n)==imageArray(m,n)" is always true. I would say to modify the code in order to load the second image, than compare the first image pixel with 0 and only afterwards to check between the two images. It really depends on what you want to happen if imageArray(m,n) is 0.

Best regards,

Adrian
