De-interlacing using area based motion compensation

A motion compensated de-interlacing method with adaptive area based motion compensation is proposed to recover the defects of interlaced video sequence. GMC is used to recover the change of the picture due to both camera motions and local motions. During the processing of a frame the areas containing enough of so called "interlaced pixels" are a subject to mathematical correction only. This allows to decrease information loss. A part of a frame is saved without changes so introduced artifacts are decreased appreciably. The proposed algorithm could achieve higher image quality of interlaced video sequences than any other usual de-interlacing algorithm on progressive devices.
