摘要：Image feature trackability ranking systems and methods are disclosed. Amethod of establishing a trackability ranking order from tracked image features within atraining video sequence at a tracking analysis device includes establishing a tracking

region within the training video sequence using a feature detection algorithm.

Trajectories of tracked image features within the tracking region are compiled using afeature tracking algorithm. Saliency metrics are assigned to each one of the trajectoriesof tracked image features based on one or more feature property measurements withinthe tracking region, and a trackability ranking algorithm that is a function of the saliencymetrics and a defined feature trajectory ranking associated with the training videosequence is determined, the trackability ranking algorithm being usable for ranking,based on trackability, tracked image features within another video sequence.
