Abstract:
Image feature trackability ranking systems and methods are disclosed. A method of establishing a trackability ranking order from tracked image features within a training 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 a feature tracking algorithm. Saliency metrics are assigned to each one of the trajectories of tracked image features based on one or more feature property measurements within the tracking region, and a trackability ranking algorithm that is a function of the saliency metrics and a defined feature trajectory ranking associated with the training video sequence is determined, the trackability ranking algorithm being usable for ranking, based on trackability, tracked image features within another video sequence.

Claim (Index 39):
A tracking analysis device comprising:\n a processor communicatively coupled with a database storing trackability ranking software code that, when executed by the processor, causes the processor to:\n establish a tracking region within a first image sequence using a feature detection algorithm; \n compile groups of tracked image features within the tracking region using a feature tracking algorithm; \n assign saliency metrics to at least two of the groups of the tracked image features based on one or more feature property measurements within the tracking region; \n determine a trackability ranking order for the tracked image features within the first image sequence using the trackability ranking algorithm, wherein the trackability ranking algorithm comprises at least sorting the groups of the tracked image features by a result of a linear combination of the saliency metrics; and \n select a subset of the tracked image features according to the trackability ranking order to facilitate an image recognition-based operation within a second image sequence according to the trackability ranking order using the trackability ranking algorithm.
