T-61.271 Visualization project description
37. Coding information into a texture

Autumn 2003

Read the project description carefully. Questions and comments can be sent to

General information

The purpose of the project work is to get hands on experience and deeper understanding on one specific area of the course. At the same time you will be forced to think on some of the more general issues that are confronted every time a visualization method is developed or used.

To complete the project you will probably need information that has not been discussed on the lectures or in the exercises. Most of the time relevant information can be easily found on the web, course books or in some cases references to articles will be given. If you have problems finding information on the subject please contact the lecturer or the assistant for hints and guidance.

The project work will be valid for one year after the original deadline.

General requirements

specific requirements

The purpose of this project is to study how textures can be used to code information and apply these methods. See Ware p. 176-187.

You should do the following

  1. Analyze the amount of information you can transmit using textures (e.g. "uncertainty principle"). Under which conditions you can see contrasts or patterns? Analyze the benefits of more complicated patterns as compared to simple Gabor textures.

  2. Make a program that takes a data set as an input and outputs a texture (for algorithm see for example Ware and Knight, Using visual texture for information display, ACM Transactions on Graphics 14(1): 3-20, 1995).
