RGB or HSV or other?

Of course I started thinking, "I wonder if I could write a pixel shader to do this?" 8P What color space are you working in? RGB or HSV or other?

However, I'm not sure if there are exactly 3 receptors per pixel. Some configuration have more receptors for green for example.<BR/>The driver of this webcam can return YUV (YCrCb) 4:1:1 (four pixels of luminance and one each of chrominance) or RGB. I'm currently getting RGB images, then tranformrming them in YUV411 before performing the necessary temporal noise reduction.. then back to RGB for the dark-frame thing.<BR/>Usually it's better not to mess with RGB images because slight errors can bring very visible artifacts. In this specific case however, it would probably be best to work at the lowest level, with what excatly the camera samples, without any drivers in between... I think !

Yes, the “beard” is gone, but I generally see more artifacts in the processed image than in the raw one, mostly on the arm and the wall.
The wall also shows some horizontal lines which I believe are due to the 32×32 squares averaging..!

But it’s still definitely cheaper than having to shave! :)

But, it's actually hinting me on the fact that the formula is wrong. It highlights the fact that the compensation that I'm applying is affecting the average brightness. <BR/><BR/>As for the increased artifacts on the wall... you are right there too, that's why I said that subtraction isn't good enough. Doing subtraction works on dark areas, but is not working on brighter areas.<BR/><BR/>In any case, it has to be added that much of this "static noise" thing started when I saw images from that old webcamera of yours.
