Opdracht 1

This assignment aims at getting acquainted with basic subjects of image processing and implementations thereof with the aid of image processing software packages. This assignment has to be done by each individual student.

CImg packet

We use the CImg library and the there mentioned ImageMagick software packet.

Install CImg version 1.1.8 and test everything on your favorite system.

Assignment

Develop a program that reads the color images, as given below, and convert them into gray value images, where the background gets the value 255 (white), the red object gets 0, the green object gets 64 and the blue object gets 128. Try to find a method that works for all the images without setting a parameter per image. This looks easy, but is rather difficult.

Report

Your report should contain:

• A description of the installation and use of CImg. This will depend on previous experiences with C++, templates, etc.
• A description of the developed methods, their advantages and disadvantages, boundaries of use like minimal or maximal variations in background color, etc.
• A measurement of the speed of the your implementation (give also details on the used hardware en software development platform) on each of the images.

The report (without the full code) should be in MSWord or PDF with a maximum of 8 pages.

Email code and report to me in zip format.
