Fast and Robust Graphic Character Verification System for TV Sets

In this paper, we present a flexible system to verify any kind of graphic TV character or symbol in television charts. The proposed approach is very robust towards translations, rotations, changes in scale and illumination variations of the graphic characters. Another important attribute of the proposed system is its speed. The system should be very fast since the characters have to be verified in a real production line of TV sets. The proposed system is composed of fast and accurate preprocessing modules in order to normalize the characters, and a PCA- based verification method. Results show a very high performance with verification rates over the 99.8%.
