<title>Deinterlacing in spatial and temporal domain</title>

Abstract

A number of deinterlacing algorithms have been proposed, which can be divided into two categories: spatial interpolation methods and temporal interpolation methods. Each technique has its own advantages and limitations. The temporal deinterlacing methods using motion compensation provide improved performance among various deinterlacing techniques. However, its performance suffers if motion estimation is inaccurate and tends to yield undesirable results when rapid motion exists. Thus, a number of spatial interpolation methods have been used along with the temporal deinterlacing method using motion compensation. In this paper, we investigate the performance of several spatial interpolation methods when they are used with temporal deinterlacing methods.
