Abstract: This paper presents an improved method for the direction-oriented interpolation (DOI) method. The technique of DOI is considered to be a very strong tool for intraframe-based deinterlacing in the literature. However, the DOI still have a problem to use wrong edge direction. To remedy this problem, we embed three steps in the DOI method to interpolate missing lines more efficiently and robustly than existing methods. In the proposed method, the spatial direction vector (SDV) data are reused and processed to prevent them utilizing in next interpolation step, resulting in the more accurate de-interlacing method. We carry out experiments to compare the proposed method with the existing methods including the edge-based line averaging (ELA) and DOI. Experimental results show that the proposed method gives better performance in objective and subjective quality than the existing deinterlacing methods.
