Project, ideas: Dr. Dmitriy Vatolin
Implementation: Maxim Makhinya
Optimization: Denis Kubasov, Alexey Moskvin

Version 1.4 - parameters loading from JOB file fixed

The filter allows to enhance image sharpness with minimum noise amplification.
New version works 5-8 times faster than previous!

Settings

Внешний вид фильтра


The set of filters allows you to change filter's intensity. Presets, which contains "borded" in their names provides additional unsharp mask.
New version supports VirtualDub jobs and AviSynth
Script example for AviSynth 


LoadVirtualDubPlugin("...\Virtual Dub\plugins\msu_sharpen.vdf","MSUSmartSharpen", 0)  
clip=AVISource("D:\Video\test.avi", false, "RGB24")
clip.ConvertToRGB32.MSUSmartSharpen(4)
Parameter for MSUSmartSharpen in the third line of the script is number of preset (from 0 to 5).

Examples

Let's feed the filter a portrait of M. Lomonosov and study the results.

Public MSU video filters
Here are available VirtualDub and AviSynth filters. For a given type of digital video filtration we typically develop a family of different algorithms and implementations. Generally there are also versions optimized for PC and hardware implementations (ASIC/FPGA/DSP). These optimized versions can be licensed to companies. Please contact us for details via video(at)graphics.cs.msu_ru. 		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.
