Motion adaptive de-interlacing with horizontal and vertical motions detection

Abstract

A motion adaptive de-interlacing technique with horizontal and vertical motions detection is proposed and its performances are examined. Object movement happens quite often in film broadcasting and normally they move horizontally, vertically, or diagonally. The movements tend to destabilize the quality of performance such as jagged effect, blurred effect, and artifacts effect, while de-interlacing technique is utilized. In our proposed method, de-interlacing begins with object motion detection, which is to ensure that the interfield information is used precisely. The proposed method also utilizes intrafield de-interlacing by median edge dependent interpolation. Median EDI, while the object movement is not detected. The simulation results show that the proposed algorithm exhibits better performances than other interpolation algorithms. © Springer-Verlag Berlin Heidelberg 2005.
