Correction to intelligent intra-field interpolation for motion compensated deinterlacing

In this paper, high performance and intelligent intrafield interpolation for motion compensated deinterlacing algorithms are proposed and modified. We present a correction to intelligent intra-field interpolation for motion compensated deinterlacing. The main intra-field interpolation algorithms that include cubic curve fitting interpolation, fuzzy edge interpolation and sub-sampled wide vector based edge base line averaging (ELA) are discussed in this paper. The main purpose of the design is to obtain high quality results and reduce the flickers and artifacts that are often introduced by conventional motion compensated de-interlacing. Furthermore, an improved intra-field interpolation is used to produce sharp edges in regions where MV is considered unreliable. The proposed algorithm produces sharp edges in this region and does not produce annoying effects in the high spatial frequency region.
