Assignment #5

The programs must be sent to the TA as MATLAB-scripts.

This time it's 'real' computer vision!
Your task: write a program that counts objects in a binary black and white image, using morphological operators.
Use the following image to check your program:

Remarks:

• A single object is defined as an 8-connected foreground-region
• Foreground is defined to be white
• You will need the following MATLAB functions:
  • imdilate (dilation)
  • bitand (intersection)
  • imabsdiff (abs. difference)
• If there are problems with data-types: uint8() converts a double-matrix to uint8 (the format you need for bitand)

Hints:

• Write a function that finds a single connected region, using formula 9.5-3 of the textbook
• Subtract the region found from the original image
• Do this until no further foreground region is left

Have fun !
