Superimposed text and scene text in video, i.e., videotext, contains important semantic clues in content analysis. In this paper we present a videotext descriptor and automatic methods for detection and representation of text in video segments. One of the methods is based on edge characterization while the other is based on region analysis. Applications of the video text descriptor are numerous ranging from video indexing and annotation, ticker-tape analysis, commercial detection, transcript analysis to cross modal querying using text and face information
