Short Description:

In the context of this course, basic knowledge required for understanding concepts concerning mostly issues of technological nature is given. The course is organised in four thematic units (analysis, algebra, analytic geometry and probabilities-statistics), in which the theoretical approach and presentation of the subjects and the respective mathematical concepts are combined with concrete examples of audiovisual technologies applications (e.g. development of algorithms for interactive audiovisual applications). Special emphasis is placed on the application of mathematical concepts through examples and drills related to sound and image technologies, using the mathematical package Matlab.

Objectives - Learning Outcomes:

The objective of the course is to provide to the students a general overview of the fondamental mathematics that are used in the audio and image processing together with the mathematics needed for 2d and 3d computer graphics.

The successful attendance of the course offers the ability to the corresponding students to:

• draw plots of functions and curves both in theory and in the computer
• know the derivatives (one or two variables) and calculate intergals
• understand analytic geometry and descrete mathematics
• write code in Octave (or MATLAB) that is applied for mathematical transforms
