High-Frequency Enhancement for RealPlayer 2.12

There have been some complaints that RV10 sometimes looks flat or "synthetic". This enhancement makes the video look more natural, and even though it is a postfilter, it takes advantage of information in the bitstream, and hence, it does not just add a uniform layer everywhere in the video.

Mathematical analysis between the source and the encoded video has shown that even though PSNR is reduced from HFE2, the visual resemblance is closer to the original.

The result is that it makes smooth surfaces, like walls, carpets, clothing, look much more natural than before, with any blocking tendencies, stair casing, and flat/dull areas much improved, in many cases completely removed.

Requirements: RealPlayer 10

Limitations: Works only with RealVideo 10
