Course Update Information

  • 01/31. CUNY faculty and students will be able to download a standalone Matlab version by creating an account using your CCNY email account at this website. On this website, go to “Matlab Portal” to create your account and download the software installer. You will need the account information to install and use the software too. It might be very slow when you downloading the real software & tools in installation. So please do not add new tools to the default but instead remove simulink etc. that you won’t use.
  • 01/31: First day of our class. Here is the Zoom Link. The Passcode will be sent before class via CUNYFirst to the emails that students used there.

Course Objectives

Computer vision has a rich history of fundamental work on stereo and visual motion, which has dealt with the problems of 3D reconstruction from multiple images, and structure from motion from video sequences. Recently, in addition to these traditional problems, the stereo and motion information presented in multiple images, a video sequence, or stereo and motion with images of expanded fields of view,  is also being used to solve several other interesting problems, for example, large-scale scene modeling, video interaction (including face and gesture interaction), panoramic video mosaicing, omnidirectional vision-based navigation, and video surveillance. This is sometimes summarized as video computing. Computer vision is playing an important and somewhat different role in solving these problems in video computing than the original image analysis approach in the early days of vision research.The course “Computer Vision” will include advanced topics in video computing as well as fundamentals in stereo and motion.

Textbook and References

Main Textbook:
   
   In the form of Lecture Notes and Slides, provided by the instructor (above).

Supplements:  

    Online References and additional readings when necessary. 

Grading and Prerequisites

The course will accommodate senior undergraduate students with background in computer science and computer engineering. Students who take the course for credits will be required to finish 4 assignments (40%), one midterm exam (40%), and  one programming project (20%, including submit a report and give a small presentation to the class at the end of the semester). The topics of the projects will be given in the middle of the semester and will be related to the material presented in the lectures.

Students are required to have a good preparation in both mathematics (linear algebra/numerical analysis) and advanced programming.
