Recently Itseez announced a minor release of OpenCV 2.4.3 with a lot of new major features: Added universal parallel_for implementation using various backends: TBB, OpenMP, GCD, Concurrency Improved OpenCV Manager, new Java samples framework, better camera support on Android, opencv2.
Hello everyone! Today i want to share my results in research of markerless augmented reality. The main idea - do fast and quality AR without those damn markers and give the ability to use real object as a target. Markerless augmented reality is very similar to marker-based systems like ARToolkit with one major difference - such technology use real object as a target for augmentation. It can be almost any kind of objects - photos, logos, beer bottle or Cola can.
