Markerless augmented reality

Augmented reality applications mixed real and synthetic data in a common frame based on some referencial marker of the real scene. Traditionally, this reference marker was a synthetic pattern included in the scene. This strategy makes easy the registration process but is not feasible to all applications. Nowadays it is common to define these markers as elements in the scene, what we call marker less augmented reality. Although reference points still are needed they can be part of the real scene. This approach can use techniques based on image processing or in the geometric reconstruction of the scene (or part of it). In this lecture we will present our current work in markerless augmented reality based on geometric registration and discuss an application of these techniques in medicine.
