Description
1. Segment some sample ANA IFF HEp 2 cell images using appropriate methods of
your choice (thresholding, morphology, etc). The example images on Blackboard
represent borderline and high positive samples. Comment briefly on the challenges
and the results you obtained. Design a suitable metric to measure how well you can
segment these cells. Explain your method.

2. Design an algorithm to determine the length of a piece of string from images. The
string can form loops and cross over itself. You are provided with sample images of
Strings 1 and 2 taken under the same conditions and you will be given the physical
length of the string for calibration. For your assignment, you should determine the
length of the string in each image example, and provide commented code and a
description of your methods. Your algorithm should be able to work on the entire
database including string 3 without modification or parameter adjustment.

String 1 = 13cm String 2 = 15.5cm String 3 = ??cm
3. Using your algorithm from Question 2 or otherwise solve the following problem.
Try to develop a GUI so that clicking on a string will show the complete path. The
scanned image is available on Blackboard.
