The main issue of this course is its presentation. I would've been fine with it if it were classroom lectures, but unfortunately, it is not. Video lessons are very long, sometimes 30min+, which could mostly be condensed in 10min+ videos, if they were better planned and executed. I watched the videos almost exclusively at 2x speed to make it bearable.
There are also tons of equations, mostly with multiple integrals, all of them handwritten. This, of course, takes a lot of time in the videos, and also make it very hard to understand such expressions. I really cannot understand why they were not embedded in the slides.
The quizzes/exercises are also unsatisfying. To pass the course, it's only required to answer to weekly quizzes, which don't require any studying at all. On top of that, there are optional programming exercises, but they are not graded, so you don't have any feedback, unless you post your results in the forums.
Video lectures are frustrating and exercises are lacking. Udacity's Intro to Computer Vision covers the first half of this course in a much more friendly and structured way. OpenCV's tutorials for Python are also a good alternative for hands-on programming material.
