Class Description: Comprehensive introduction to computer vision providing broad coverage including low level vision (image formation, photometry, color, image feature detection), inferring 3D properties from images (shape-from-shading, stereo vision, motion interpretation) and object recognition. 

A companion course, CSE252B, Computer Vision II is taught in the spring quarter. 4 units.

 

Required Text: “Computer vision: A Modern Approach,” David A. Forsyth, Jean Ponce, Prentice Hall, ISBN: 0130851981

 

Prerequisites: Linear algebra and Multivariable calculus (e.g., Math 20A & 20F), programming, data structure/algorithms (e.g., CSE100).  Probability can also be useful.

 

Programming: Assignments will include both written problem sets and programming assignments in Matlab.  Students can either purchase the Matlab student edition or use copies available on University machines such as are available in the APE Lab.

 

Grading:

            Assignments:     60%

            Final Exam:       40%

 

Late Policy: Written homework will be due in class and accepted thereafter with a penalty of 10% per day starting from the due date. Programming assignments will have a hand-in procedure described with the assignment, and also has a 10% per day late penalty.  No assignments will be accepted after the graded assignments have been returned or the solutions have been released. 

 

 

Assignments:

Homework 0: Getting Started with Matlab, Due Thursday, 1/13/05

Homework 1: Photometry & Cameras

Homework 2: Constructing an image mosaic

            Test Images: piscine1.gif, piscine2.gif,  piscine3.gif, piscine4.gif,  piscine5.gif

Homework 3: Corner detection

            Test Images: image1.pgm, piscine1.pgm

Homework 4: Stereo, Due Tuesday 3/2/04.  Test images are at: http://www.ijrr.org/contents/20_07/abstract/banks/1196-1.html
