Abstract
Object tracking for device input can be improved by utilizing various tracking parameters to correlate objects between analyzed image frames. In some embodiments, relatively low resolution infrared cameras can be used for object tracking, in order to conserve resources on the device. Intensity segmentation can be used to identify potential objects of interest to be analyzed in captured image data. One or more tracking parameters, such as size, shape, and/or distance, can be specified for each of the objects in order to correlate objects between images. The correlations can be ranked by confidence or other such metrics in order to improve overall accuracy. Tracking data can also be stored for a period of time such that objects that are not clearly distinguishable for a while but then reappear can again be correlated with objects from earlier images.
