SSTT NFT - Natural Feature Tracking

SSTT NFT is one of the tracking modules in SSTT core. Originally SSTT was conceived to replace the venereal ARToolkit as the standard tracker in osgART. Hence, the original implementation did only consider marker tracking but already abstracted tracking targets, localization and tracking on a higher level. The video below shows a prototype of SSTT with natural feature tracking using a non-optimized SURF descriptor. Due to the rather heavy weight implementation of using SURF without additional optimizations this part is not viable for the mobile version of SSTT. Depending on compile settings in the SSTT desktop version. Further development in SSTT concentrates on a radial histogram based descriptor that is in recall rate equivalent to SURF but with less dimensions and only suitable for a single target. SSTT NFT has been heavily enhanced in SSTT2.
