Abstract
Aspects of the present invention relate to systems and methods for refining text segmentation results. Non-text, line elements in a text map may be detected and removed from the text map. Pixels associated with vertical and/or horizontal lines may be identified in the text map based on a background-color constraint, a directional color constraint and a continuity constraint. Run counters and run-reset counters associated with a direction may be used to identify pixels meeting the continuity constraint.
