Hello!
I've written a avisinth filter : ExpSat (http://expsat.sourceforge.net) As the name say, it's a filter which works on saturation by elevating its curve .. better to take a look on examples in the url ! Please comments! Last edited by Guest; 8th July 2005 at 22:20. |

Hmmm... this filter looks interesting.. Maybe I could use it in my Matrix script... Take a look here. The current Matrix script destroys skin tones and such.

Hello brabbudu,
you can use YUV-colorspace as well (in the digital domian the correct term is Y'PbPr), you don't need to convert to HLS. Do you know a vectorscope? This is a x/y plot of the Pb an Pr component. The lenghts of a vector (0,0->Pb,Pr) is the saturation. So you get similar results by just manipulating Pb+Pr. Maybe you can gain speed if you use this method hanfrunz |
