Looking for DirectShow Denoise filter

Analogue capturing is often done using an MJPEG codec. Unfortunately DCT based codecs are sensitive to noise, so it would be good to have a denoise filter put before the MJPEG encoder. In VirtualVCR you can add DirectShow filters, but I couldn't find any DirectShow filter on the net except the one from AlparySoft (which is not the best of breed). There are many good denoisers available for VirtualDub and AviSynth, but I think noone has ever thought about a DirectShow solution. Would someone mind to port / adapt his / her (;)) filter to DirectShow? bb

All we need is the fully explained, easy to use SDK/framework examples of the sort provided by Avery Lee and Ben Rudiak-Gould and there'd be hundreds :) But there isn't :( regards Simon

Download FFDShow, set it to process raw video, and have it filter your video; you can even use the avisynth part of it to specify the filter(s) at your will. You may need to use graphedit and build a .grf file, if your encoder is able to read that. Last solution is use MakeAVIs (it seems it doesn't work that well) to build a fake AVI from the .avs script.

Never thought of using ffdshow as a DirectShow denoiser; I'll try it. But I don't think the other options you mentioned can be used for capture purposes. bb

Interesting - I've started downloading the SDK - should get it all by Xmas :) Then I can see how easy it is to use :) regards Simon

Here's a good reference: I plan to enter this field fairly soon.

Well I downloading the SDK (220MByte ! ) twice and both times it locked my machine up when I tried to run it - it seems to try to uncompress itself and fails (badly) :( Simon

Are you talking about this one (second link): It's 182 MB. Installs fine for me.

No - your link leads me to dx90bsdk.exe (says its 218MByte download on my system :confused: ) I searched and previously downloaded dx90asdk.exe (223,367kByte in explorer) I think I've made the point about it not being as easy as Avery's or Ben's (et al) frameworks - and I haven't even got to try using it yet :mad: regards Simon

if i remember well, those SDK can be decompressed with winrar (and perhaps winzip) as they are just self-extractive archive (for the 8.1 at least ;) ) Try to decompress it like that first and then run setup.exe (though you can read doc/play with samples w/o installing it).
