CS 659 Image Processing
Exam Two
Name: Student ID #:
Covering Lectures 7~13. There are 4 questions. Each is 25 points.
1. (a) Suppose that A is an image of 6x13 and B is the structure element (note: the origin is
located at the center) shown below.
A: B:
0000000000000 0 1 0
0111110001110 1 1 1
0111110001110 0 1 0
0111110001110
0111111111110
0000000000000
What is the result of A ⊕ B? What is the result of A B?
(b) Draw the quadtree representation for the following image. What is the size of a block represented
by a node at level 2? Assuming the root is labeled as level 0, the next downwards are level 1, level 2,
and so on.2. (a) Apply a two-step distance algorithm to obtain the chessboard distance transform on the
following image.
(b) What is the skeleton from the above distance transformation?
(c) What is the disadvantage of the skeleton obtained by this method?
3. Apply the thinning algorithm to the following binary image. (Use 8-neighbor) Note that the
deletion of non-simple pixels starts from North, and then South, West, East, and repeat the deletion
until no changes.
4. How can we obtain the chain codes and crack codes by using the border following
algorithm considering 8-connectedness?
