Presentation Transcript

  1. Dan Witzner Hansen DiakoMardanbeigi Email: witzner@itu.dk/dima@itu.dk Introduction to Computer Graphics and image analysis

  2. Usual get to know each other About the course Appetizer Rudimentary Today

  3. Lectures Thursdays - 9.15-12, 2A14 Exercises room 4A54 / 4A58 Homepage and questions please use the blog: http://blog.itu.dk/SIGB-F2011/ TA: LiseMøllerPedersen(lmp@itu.dk) Course info

  4. Parts from various books Lecture notes Links Literature!

  5. 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) Exercises and Exam

  6. Who? Dan Witzner Hansen?

  7. Current research – Mobile eye tracking

  8. Current Research –Domotics & Elderly Photos: DiakoMardanbeigi

  9. Selected brief presentations: • – Name? • – Your expectations for the course? Who are you

  10. 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 My Teaching

  11. Course Overview Sky Tree Athlete Horse Horse Horse Horse Horse Shape from X??? Horse Grass

  12. What about obama?

  13. Course Overview

  14. About using photoshop / Maya / 3DSM etc, but about some of their basics (platform independece) Image analysis? The course is not:

  15. 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 Course Goals

  16. Games (Graphics, Effects, Computer vision) HCI (e.g. computer interaction) Interaction design Pervasive computing Related to what at ITU

  17. Almost everywhere and increasing • Homes • Industry • Medical • Interaction • User interfaces (e.g. an important part of WPF) Used where??

  18. Multimedia & User interface - WPF http://www.wpftutorial.net IntroductionTo3D.html

  19. Interaction

  20. Science

  21. Medical ImaginG Recognitionofheartmovements Automatically detected haemorrhages and micro aneurysms in digitized fundus images Diagnosisofarteritis (gigt)

  22. Industry

  23. Movies (special effects, improve quality etc) Photo manipulation, correction Games Homes

  24. Combine Computer Vision and image analysis Courtesy Claus Madsen, AAU

  25. Does it work – Something you will be able to make after the course

  26. Lecture 16. February has been moved to Friday 11. February (9.15-12) Exercise 16. February has NOT been moved… Week 3 changed

  27. Today’s goals: • Learn enough matlab to get started. • Review some basics of Linear Algebra Matlab tutorial and Linear Algebra Review
