  2. Original image

  3. The result of Otsu algorithm • Threshold=144

  4. The result of Kapur algorithm • Threshold=117

  5. My method_1 Part 2 Part 1 Part 3 Part 4

  6. The result of method_1 • Using Otsu algorithm Part 1=132 Part 2=131 Part 3=135 Part 4=134

  7. The result of method_1 • Using Kapur algorithm Part 1=101 Part 2=187 Part 3=117 Part 4=191

  8. The result of method_2 • Threshold=80

  9. Conclusion • The results of Kapur algorithm are better than the results of Otsu algorithm. • The result of method_2 seems to be the best outcome, but it needs more times and some letters of the words have problems.
