Sheet 1 (Introduction)
1.

Electromagnetic and acoustic are two different imaging modalities. The source energy is passed
(or reflected) through (or by) the objects to be imaged. This energy is then senses and converted
to a digital image.
a) Mention some applications for each modality
b) Choose one imaging application for each of the two modalities and give details about it.

2.

Explain how the image shown below is typically produced

3.

What are the two main application areas of digital image processing?

4.

There are no clear-cut boundaries in the continuum from image processing at one end to
computer vision at the other. However, one useful paradigm is to consider three types of
computerized processes in this continuum: low-, mid-, and high-level processes. Explain.

5.

The invention in the early 1970s of computerized axial tomography (CAT), also called
computerized tomography (CT) for short, is one of the most important events in the application of
image processing in medical diagnosis. Explain how the CAT image is constructed.

6.

Describe how, in general, digital images are formed.

7.

Mention some example for gamma-ray imaging

8.

Show how the X-rays are generated for the purpose of medical imaging and mention one example
of the medical x-ray imaging.

9.

Explain the fluorescence microscopy as one example in Ultraviolet light imaging.
