ECE 4310/6310 Introduction to Computer Vision

The purpose of a computer vision system is to take data (usually in the form of one or more images) and produce information. For example, a computer vision system might inspect bottles for proper volumes, identify abnormal tissue in a medical image, recognize a fingerprint to allow entry to a building, or tell an automated door when it is safe to close. This course teaches the mainstream theories of computer vision used to build such systems. Several examples (such as optical character recognition) are implemented in assignments. It is assumed the student has a solid mathematical background and is proficient in C programming.

Semester project for ECE 6310 students.

Some information on the software tools you will need for this course.

Many of the images used as examples during lectures, and for assignments. Some helpful pieces of C code from lectures and for assignments.

An on-line free repository of textbooks, Wiki pages, data sets and other resources related to computer vision.

Here is the tentative outline for the semester. Dates and topics are subject to change.
