MATLAB: How to make this code work? i am trying to threshold an image.

digital image processingimage analysisimage processing

im = imread('image.bmp');
x = []; %creating empty matrix for x
y = [];%creating empty matrix for y
for i = [1: size(im,1)]
    for j = [1:size(im,2)]
        if 120 < im(i,j) < 200 {
            x = [x,i]; y = [y,j];
            i = 1; j = 1;              
            end
        }
    end
end

Best Answer

if true
  %Threshold
x = []; %creating empty matrix for x
y = [];%creating empty matrix for y
for i = 1: size(im,1)
  for j = 1:size(im,2)
      if im(i,j)<200 && im(i,j)>50 
          im(i,j) = 255;
      else im(i,j) = 0; %%else set rest of pixel values outside the range to 0
          end
    end
end
end
