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 79):
A computer program product embedded in a non-transitory computer readable medium comprising instructions executable by a computer processor for establishing a trackability ranking order from tracked observed image features, the instructions being executable by a computer processor to execute processing comprising:\n accessing a database storing a trackability ranking algorithm established using tracked training image features within a training video sequence; establishing a tracking region within a query video sequence using a feature detection algorithm; compiling trajectories of tracked observed image features within the tracking region using a feature tracking algorithm; assigning saliency metrics to (1) each one of the trajectories of the tracked observed image features based on one or more feature property measurements within the tracking region, and (2) a surrounding environment of the tracked observed image features in the tracking region; determining a trackability ranking order for the observed image features within the query video sequence using the trackability ranking algorithm, wherein the trackability ranking algorithm is a function of the saliency metrics and a defined feature trajectory ranking associated with the training video sequence, wherein the trackability ranking algorithm comprises at least sorting the trajectories of the tracked observed image features by a result of a linear combination of the saliency metrics; and facilitating at least one of an image-based recognition search, a video segmentation, or a pose estimation and mapping system according to the trackability ranking order using the trackability ranking algorithm.
