Horizontal scrolling text processing for frame rate conversion

In this paper, we propose a novel method reducing motion artifacts in horizontal scrolling text (HST) area which has been frequently occurred during frame rate conversion (FRC) processing. The proposed method takes place in the following two steps: HST area detection and motion vector (MV) correction. The most dominant MV in each horizontal line is referred to as a block line motion vector (BLMV) and its direction and magnitude are used to detect HST regions. MVs in the HST regions are corrected in order to suppress the motion artifacts. It is advantageous to improve the performance of various motion-based image processing applications such as FRC. Its merits and performance in motion artifact reduction could be verified through a set of visual experiments.
