Yes, this course is very good: https://youtu.be/2uiulzZxmGg

In addition, you can try to work through a serious project related to computer vision to help you solidify concepts. I worked used Style Transfer as my motivating example: https://harishnarayanan.org/writing/artistic-style-transfer/

This is a great resource. I give it to people who need to learn about convolutional neural networks.

However let's keep in mind that the field of computer vision is much vaster than that. Deep learning approaches have been very successful at solving problems in computer vision, but not all of them and not without drawbacks. I believe any course on classic computer vision will give him more insight as to what challenges computer vision aims to solve, how, and what approach might solve what problem.
