An adaptive training-free feature tracker for mobile phones

Jan Herling, Wolfgang Broll
2010 Proceedings of the 17th ACM Symposium on Virtual Reality Software and Technology - VRST '10  
However, most existing approaches do not yet achieve sufficient frame rates for AR on mobile phones or at least require an extensive training phase in advance.  ...  In contrast to other feature based approaches on mobile phones, our implementation may immediately track features captured from a photo without any training.  ...  The adaptive tracker starts with an initial number of features n to be used and a lower and upper boundary for n.  ...
