MSU-Samsung Deinterlacing Project

• Method ideas, project: Dr. Dmitriy Vatolin
• Implementation, ideas: Denis Kubasov, Sergey Putilin, Maxim Makhinya

The filter is designed to suppress comb effect, also known as interlacing, in motion pictures. As opposed to other available filters, MSU Deinterlacing uses a balanced combination of 8 filters to ensure better picture quality.

Examples

We shall compare MSU Deinterlacing Filter to Smart Deinterlace (one of the best available filters written by Donald Graft) using 3 test sequences.

The first example is frame No. 9 from sequence ‘Helicopter’.

A frame from the sequence	A fragment of the frame
The fragment processed by MSU Deinterlacing	The fragment processed by Smart Deinterlace

It’s easy to see that image feature outlined in red looks much better on the left picture. Smart Deinterlace made it blocky, while MSU Deinterlacing did better job at image reconstruction.

The next example:

Consider fragment of the frame:

The next example is fragment of frame No. 92 from Schumacher sequence.

Frames from sequences tennis & mobl:
AlparySoft, Decomb and MSU SMC deinterlacer.

This filter was developed from October 2002 to May 2003 by group and from May 2003 in collaboration with SAIT (Samsung Advanced Institute of Technology) so currently filter is unavailable due to contract limitations.
