Hi, Can anyone recomment an efficient realtime algorithm for seperating text with arbitrary orientation from an arbitrary image? Thanks, Ronen goldshtein

Information costs as Vlad would say..

This link: http://www.docstoc.com/docs/44380298/1011691103 provide a comprehensive survay of text extraction methodologies, seems to me as if the most adequate approach is connected component analysis.
