  • Discussion section room has changed to Kleiber 3
  • Matlab is available for free from the campus software site here.
  • Info on IET Virtual Labs for MATLAB remote access
  • Instructions on obtaining a Graphical Interface (e.g., for MATLAB) via SSH to CSIF machines
  • Sign-up for our class piazza here (access code sent via email).

Course Overview

Computer vision is the study of enabling machines to "see" the visual world (i.e., understand images and videos).   In this upper-division undergraduate course, we will explore several fundamental topics in the area, including features and filters, grouping and fitting, and recognition.


Basic knowledge of probability and linear algebra; data structures, algorithms; and programming experience.  Experience with image processing or Matlab will help but is not necessary.  Please talk to me if you are unsure if the course is a good match for your background.


Computer Labs (w/ Matlab)
  • Matlab is available for free from the campus software site here.
  • CSIF labs 67, 71, 75.  Lab info and account info here and here.  Remote access info here.  pc1-pc60 have Matlab.  
  • Academic Surge 1044 and 1116.  Lab schedule can be found here.  ECS 174 is reserved for our class; other empty slots are available as well.  Remote access info here.
  • IET Virtual labs here.  Please read the FAQ.


Rather than emailing questions to the teaching staff, please post your questions on Piazza.  Our class page: piazza.com/uc_davis/spring2018/ecs174
While we encourage you to help your fellow students, please do not post assignment solutions.


We will use Canvas for problem set submissions and grading.  Our class page: https://canvas.ucdavis.edu/courses/225624


Students will be responsible for participating in class and on piazza, completing 4 problem sets, and completing a final exam.


The final grade will be determined by:
  • Class and piazza participation (5%)
  • Problem sets (60%)
  • Final exam (35%)
