85: Computer Vision in Elixir with Cocoa Xu

We talk with Cocoa Xu about his PhD robotics project and his related Evision project that creates Elixir bindings to the OpenCV library. The project enables computer vision in Elixir much easier by building on existing projects. We learn about the kinds of features this enables and how it can target embedded devices as well. His goal of a clustered, collaborative, hoard of Elixir robots is terrifyingly fascinating! 😄
