3D IMAGING Introduction and Administration

Contact details  Sasha Apartsin  Web Page   On the web page  Slides  References  Assignments submission guidelines  Prep. Material for the exam 2

What this course is about?  Physical 3D object/scene  Shape, Position, Motion, Color, Density  Measurements  Single Image or multiple images of a scene  Ultrasound /RF waves reflected/emitted by the objects  Computer Vision  Understand real world from images/measurements  Computer Graphics  Generate images from a world model 3

Grading  X: 65% multiple choice “close-material” final exam  Y: 20% multiple choice “close-material” midterm  W:15% mandatory assignments  G=0.65*X+0.2*max(X,Y)+0.15*W 4

Assignments  Work in pairs (no triples, but single is OK)  Each pair submit X multiple-choice questions with solutions for each subject studied  All submitted questions and solutions with explanations are published  Exams will be combined from the submitted questions with (probably) small modifications  Provided submitted questions are of good quality 5

Questions  Shouldn’t be too tricky. Those who listened in the class should be able to answer  Shouldn’t be too trivial. Those who wasn’t in the class should not be able to answer  10 questions should cover different aspects of the studied subject  Numerical multiple choice questions are ok 6

Finally  Detailed submission guidelines will be published shortly  Submissions via  Submission deadline will be published after each subject is covered in class  There will be about 10 assignments  Disclaimer: if submitted questions are no good or are all the same, the exam will contain “surprise questions”! 7

Tips A. Listen in class and think about what questions could be asked. Make notes. B. Spend an hour per subject for writing down these questions C. Ideally, A+B above should get you 100 on this course 8

Tentative Plane 9  Computer Vision  Image Formation and Camera Model  Shape from multiple views  Shape from video  Computer Graphics  Modeling and representation of 3D objects  3D rendering  Motion Capture  Ultrasound and Computer Tomography  Fun applications 3DTV, Kinect etc.
