Udacity: Introduction to Computer Vision

This course provides an introduction to computer vision including fundamentals of image formation, camera imaging geometry, feature detection and matching, multiview geometry including stereo, motion estimation and tracking, and classification. We’ll develop basic methods for applications that include finding known models in images, depth recovery from stereo, camera calibration, image stabilization, automated alignment (e.g. panoramas), tracking, and action recognition. We focus less on the machine learning aspect of CV as that is really classification theory best learned in an ML course.

The focus of the course is to develop the intuitions and mathematics of the methods in lecture, and then to learn about the difference between theory and practice in the problem sets. All algorithms work perfectly in the slides. But remember what [Yogi Berra](http://yogiberramuseum.org/just-for-fun/yogisms/) said: In theory there is no difference between theory and practice. In practice there is. (Einstein said something similar but who knows more about real life?) In this course you do not, for the most part, apply high-level library functions but use low to mid level algorithms to analyze images and extract structural information.

Why Take This Course?
Images have become ubiquitous in computing. Sometimes we forget that images often capture the light reflected from a physical scene. This course gives you both insight into the fundamentals of image formation and analysis, as well as the ability to extract information much above the pixel level. These skills are useful for anyone interested in operating on images in a context-aware manner or where images from multiple scenarios need to be combined or organized in an appropriate way.

What are MOOCs?
MOOCs stand for Massive Open Online Courses. These are free online courses from universities around the world (eg. Stanford Harvard MIT) offered to anyone with an internet connection.
How do I register?
To register for a course, click on "Go to Class" button on the course page. This will take you to the providers website where you can register for the course.
How do these MOOCs or free online courses work?
MOOCs are designed for an online audience, teaching primarily through short (5-20 min.) pre recorded video lectures, that you watch on weekly schedule when convenient for you.  They also have student discussion forums, homework/assignments, and online quizzes or exams.

I think this is the best computer vision MOOC as it covers almost all the traditional computer vision techniques (as opposed to deep learning). This is a proper graduate-level course with rigorous mathematics and the instructor has good sense of humour too. My advice for or students planning to take this course is, after the first few lessons, you don't need necessarily need to follow the course order, just jump the the topics you're interested in or you might not finish the whole thing. I have been following this course on and off for 3 months but still yet to finish half of it.

Simply the best course I have ever taken. The content is interesting, the presenter is engaging and the concepts are explained clearly and intuitively. Mixed through the lectures are matlab/octave exercises which are really great for checking understanding of the lecture material and give a good amount of practice in the practical application of the knowledge you are getting. Really wish some of my engineering lectures at university could compare to the quality of this course.

Prof. Aaron Bobick makes the class interesting with his humor. He generates interest for people by covering the topics at a faster pace yet in a way understandable for newbies.
