Motion decision feedback deinterlacing algorithms

As an effort to improve the video quality of a digital TV (HDTV) system, a robust motion adaptive deinterlacing algorithms based on motion decision feedback rules are proposed, which, in principle, utilizes the motion decision information of the past and the current pictures. With the proposed algorithm, visual artifacts due to the failure in detecting a fast repetitive motion embedded in an interlaced video sequence can be significantly reduced. Hence, with the proposed algorithms, much more pleasing video quality can be realized for the HDTV systems than typical motion adaptive deinterlacing algorithms.
