Brief overview:

This course is intended for graduate students and advanced undergraduates who are interested in processing image and video data, in order to extract information about the scene that is being imaged.� There is no textbook for the course.�Handouts and papers will be made available online.� A recommended text is Forsyth and Ponce�s book �Computer Vision:� A Modern Approach�, but it covers topics that we won�t and vice versa.

The course has a more algorithmic flavor than many introductory computer vision courses.� We will focus on efficient algorithms, precise problem definitions and methods that work well in practice.�

We use material from various areas of algorithms and mathematics as well as requiring programming assignments, but this course does not teach algorithms, mathematics or programming. Thus we expect that students have good programming skills (using C or C++), a good mathematics background, and knowledge of algorithms. Students will be expected to pick up new mathematical and algorithmic techniques during the semester, as covered in lecture, and to relate the concepts from lecture to the programming assignments.

Assignments:

Assignment 1, filtering and edge detection
Assignment 2, project proposal

To hand in an assignment, login at http://cms.csuglab.cornell.eduwith your Cornell netid and password and go to assignment 1 to upload a single zip or tar file with your source, executable and writeup.��

Data for the final project:

Data files are available at http://web3.cs.cornell.edu/cs664/.�The README file provides information about the data files and sensor configuration.� For those who might care, the camera lens is Pentax Model#: C30405TH (4.8mm F/1.8).

Movies corresponding to the raw data files may also be useful, and are available as log1, log2part1, log2part2 and log2part3.� You may need the FFDShowcodec to view them.

Course Requirements:

There will be a few short in-class quizzes, two assignments and a final project. The assignments and project will require programming, testing with image or video data, and a well thought-out write-up explaining what was done and what was learned.

The programming is probably best done in C or C++ due to the availability of libraries such as OpenCV, but Matlab can also be an option (Java is not recommended).�
