Abstract
A mobile platform visually detects and/or tracks a target that includes a dynamically changing portion, or otherwise undesirable portion, using a feature dataset for the target that excludes the undesirable portion. The feature dataset is created by providing an image of the target and identifying the undesirable portion of the target. The identification of the undesirable portion may be automatic or by user selection. An image mask is generated for the undesirable portion. The image mask is used to exclude the undesirable portion in the creation of the feature dataset for the target. For example, the image mask may be overlaid on the image and features are extracted only from unmasked areas of the image of the target. Alternatively, features may be extracted from all areas of the image and the image mask used to remove features extracted from the undesirable portion.
