(I will look at the timestamp of the submitted file)
  1. Write a matlab program "vowel.m" that uses binary image processing methods to find instances of the lower case letters 'e' in the following relatively noise-free scanned texts of the same font and size:
    1. test image 1

      2. Click Right Mouse button (and choose Save As)to download in TIFF or in GIF, OR  copy from /net/hi2/cpl/classes/cs7321_98_winter/images/ps1-ex1.tiff
       

    2. test image 2

      3. Click Right Mouse button (and choose Save As) to download in TIFF or in GIF  OR  copy from /net/hi2/cpl/classes/cs7321_98_winter/images/ps1-ex2.tiff
       

    3. test image 3

      4. Click Right Mouse button (and choose Save As) to download in TIFF or in GIF  OR  copy from /net/hi2/cpl/classes/cs7321_98_winter/images/ps1-ex3.tiff
       

    The output should be three images in which the detected letters appear highlighted in a color, and all other text and symbols appear in black.
     
  2. Do the same for the letters 'a', 'i', 'o', and 'u'. In other words make it general for all five of the vowels.
  3. EXTRA CREDIT Find some other image where a similar form of binary vision could be used to detect something.
  4. EXTRA CREDIT Use some other method to do the same
  5. WHAT to TURN IN?
  6. ENJOY.
