Static text region detection in video sequences using color and orientation consistencies

Motion compensated error of the static text in the frame rate conversion (FRC) is most annoying artifact because people cannot read it. In this paper, we present a novel static text region detection algorithm for preventing the motion compensation error in FRC. We use some consistent properties of the static text that the color of the text is spatio-temporally consistent and the orientation of the text boundary is preserved in consecutive frames. We observe whether each pixel's consistency is preserved for several frames, and then we decide it as a static text. Our algorithm can not only perfectly extract the static text region but also easily be implemented in hardware because of its ease.
