Answer 1

I = im2double(imread('Untitled.png'));
I = im2bw(I(:,:,1), 0.5);
L = bwlabel(I);
I(L== L(167, 10)) = 0;

Try this:

rgbImage = imread('untitled.png');
subplot(3,1,1);
imshow(rgbImage);
axis on;
title('Color Image', 'FontSize', 22);

binaryImage = rgbImage(:,:,1) > 128;
subplot(3,1,2);
imshow(binaryImage);
title('Binary Image', 'FontSize', 22);
axis on;

   Now get rid of lines.
  % Erase top line
  binaryImage(1,:) = false;
  % Erase bottom thick line and edge line.
  binaryImage(165:end,:) = false;
  % Erase left border line
  binaryImage(:,1:2) = false;
  % Erase right thick line and edge line
  binaryImage(:, 211:end) = false;
  subplot(3, 1, 3);
  imshow(binaryImage);
  title('Cleaned Binary Image', 'FontSize', 22);
  axis on;

Can this be automated, because I wants to use it in more number of images and their may also vary. So a direct cropping/assigning 0 values to selected pixels won't work!

Please help

Yes. See the FAQ.

@calvin Li, all browsers that I've ever seen will let you just click on the "the FAQ" link and will take you there. Also if you hover over that link, it will show you the link URL address in a status bar or tooltip string somewhere.

Since your browser doesn't have that feature, or your didn't know about it, here is the full link below:

Hi Image Analyst Sir,

Sorry, the statement is not that i can not find the link but i can not find the answer about the automaticly remove unwanted line from image. as the attached, there are some number and english charaters w/ a interference curve. Just like Parth Dethaliya has mentioned. I want to remove the curves by matlab but didn't find any solution to achieve the goal. if you have any suggestion, please let us know. thanks
