EXERCISES AND EXAM

Exercises are not mandatory but recommended

Assignments are mandatory and have to be handed in to the TA in groups of 2-3 persons AND at the end of the semester as groups.

PLEASE form the groups before next lecture.

The exam is oral with written material (assignments)

WHO ARE YOU

Selected brief presentations: – Name? – Your expectations for the course?

MY TEACHING

Rely on reading material for precise details. Try to give you a basic intuition, another angle on the

material, an instructive example. Help you read the books: Try to explain the most

difficult parts well, leave the easy parts to yourselves. You are expected to read in advance to have an

idea about the lecture, but you should expect to use more time per page after the lectures.

I speak fast, but will try to slowdown

Feedback ALWAYS welcome – please :D

WHAT ABOUT OBAMA?

COURSE OVERVIEW

Rudimentary linear algebra / matrix calculations

Matlab

Computer Graphics C# and matlab

Image analysis Matlab / hints to C#/WPF

Computer Vision Matlab

THE COURSE IS NOT:

About using photoshop / Maya / 3DSM etc, but about some of their basics (platform independece)

Image analysis?

COURSE GOALS

Develop interactive computer graphics applications in C# and DirectX /XNA Explain and implement geometric and projective transformations of images

and 3D objects (2D and 3D, pinhole cameras, stereo cameras). Employ rasterization of geometric primitives (drawing lines, polygons, etc.) Texture-mapping, shadows, hidden surface removal and lighting. You will be able to clearly explain and implement standard operations on

images (such as image filtering and image morphology) in Matlab. You will be able to clearly explain and use basic linear algebra in Matlab. You will be able to adapt appropriate vision and graphics methods to a

given problem.

Material may be challenging during the course. Focus on understanding not proofs.

Hope to share our enthusiasm about the contents and their possibilities
