These online courses (available at  https://zhaoping.thinkific.com/ ) include

A very brief introduction of what is known about vision experimentally

A very brief introduction to simple mathematical methods for computational vision

The efficient coding principle

Visual attention and V1 Saliency Hypothesis

Visual decoding and recognition

You can mix and match them for graduate courses in (e.g.,) "Introduction to Vision", "Systems Vision Science", and "Computational Vision". They have been used for teaching in the University of Tuebingen, and are also suitable for self-study.

Questions and comments are most welcome!
