Computer Vision is at the heart of the coming Mixed Reality future and is an important skill to be aware of and even dive into! As developers we are lucky to have a rich resource that is OpenCV that makes it straightforward to learn core tenants of computer vision. I will use Python to demonstrate power features of OpenCV such as image tracking, Snapchat like filters, and face detection. I will then go into how OpenCV can be utilized in iOS and Android applications to add power (and fun!) to a wide array of applications.
