Tracking Essentials

VisionLib focuses particularly on tracking objects, using different tracking techniques centered around what we call Enhanced Model Tracking.

Model Tracking combines 3D graphics with computer vision and let's you use 3D and CAD data for detecting, localizing and tracking physical objects in the video stream.

This section addresses basic + essential, as well as advanced topics while using VisionLib's tracking techniques during development.

Partly step-by-step, we describe core components, processes and techniques when working with model tracking. While some cases are explained at the example of Unity3D, the core concepts can be transferred on other platforms and systems.
