Computer Vision has always been seen as a dark art by beginners and programming students, although sometimes it's simpler than you would expect. One major cause for this is the lack of visual output from the algorithms and easy to use visualization and development tools. To solve this problem I developed cvedu, an open source, web-based IDE to teach computer vision by employing visual programming concepts. In this talk I will describe how I developed cvedu, using open source web technologies such as React and WebGL, and how you can use it to make computer vision more fun and easier to understand.
