Abstract: High quality video interpolation is always desirable, since the definition of video display devices is improving. It is always necessary to port a video of lower quality to higher quality displays, such as the conversion of SDTV videos to HDTV videos. In this paper we will present a further improved Edge-Directed Interpolation (EDI) by proposing a new sampling pattern and subsequently give a fast approach for the enlargement of a SDTV (704×480) video into a HDTV (1280×720) video (1.5 time enlargement). Experimental results show that our approach has a better performance in terms of edge quality compared to that of the New Edge-Directed Interpolation (NEDI) in the literature. More-over, the fast approach is 50% faster and the visual quality is also better than the NEDI.
