New filter version!

Project now is in beta-testing stage

Filter is used for video quality improving:

• HDR (High Dynamic Range) compression
• Shadowed colors and details restoring
• Light-struck colors and details restoring
• Faded colors restoring

Settings

New version improvements:

• Speed
• Interface usability
• Frame processing algorithm was changed for more efficient HDR frames rendering

Settings dialog allows to change:

• Frame illumination only
• Frame colors only
• Frame illumination and colors simultaneously

Filter's interface

Correct illumination

Filter's interface - illumination enhancement

1. Source image has very bright and very dark region - Processing image has HDR frames. Control using makes contrast low.
2. Brighten dark region - Allows to illuminate dark frame regions. Dark regions won't be processed if control value is equal to zero.
3. Reduce bright region - Allows to restore light-struck frame regions. Light regions won't be processed if control value is equal to zero.

Correct colors

Filter's interface - color enhancement

1. Correct colors - Saturation setting control. If value is set in zero saturation won't be changed. Note: recommended in use with Auto Levels.
2. Auto levels - Automatic levels correction. One reflects source frame illumination to all allowed illumination range.

Let's consider job of the filter on a test rollers.

Public MSU video filters Here are available VirtualDub and AviSynth filters. Commonly we develop a whole family of some kind of a filter. Generally there are also versions optimized for PC and hardware implementations (ASIC/FPGA/DSP). These optimized versions can be licensed to companies.

MSU filters statistics	MSU filters for companies We are working with Intel, Samsung, RealNetworks and other companies on adapting our filters other video processing algorithms for specific video streams, applications and hardware like TV-sets, graphics cards, etc. Some of such projects are non-exclusive. Also we have internal researches. Please let us know via video(at)graphics.cs.msu_ru if you are interested in acquiring a license for such filters or making a custom R&D project on video processing, compression, computer vision.
