Abstract
A system and method for processing segmentation tags is disclosed. The system comprises a neighborhood analysis module, transition analysis module, and a tag cleaning module. The neighborhood analysis module generates a neighborhood block tag prediction from a block of segmentation tags having a first predefined relationship with a current tag. The transition analysis module generate a transition block tag prediction from a block of segmentation tags having a second predefined relationship with the current tag. The tag cleaning module modifies selected segmentation tags based on the neighborhood block tag prediction and the transition block tag prediction. The method comprises identifying a current segmentation tag to be cleaned; generating a tag prediction from a plurality of segmentation tags having a predefined relationship to the current segmentation tag; and generating a cleaned segmentation tag for the current segmentation tag based upon the current segmentation tag and the tag prediction.
