Saturate video
May 11th, 2010, 11:17am  
Hi Guys

Extreme noob here.

So I'm capturing my video device using Capture and processing.video.* But before I feed it onwards for further analysis I really want to do some calibrating of the image. Specifically, I think I want to saturate the video somewhat so that colours stand out more obviously. Eventually feeding this into colour tracking. But the image is reasonably dull and grey. So a saturation stage would be great.

I've done some searching, and there is talk about going through the pixels array and increasing a value (HSB I think) before converting it back into RGB. But I don't know what format my video is upon being processed by processing, nor how to distort the image at the pixel level.

Maybe there is a simple saturation function that I can plug my video feed into, but I have not been able to find this.

Please help, the project I'm working on needs to be happening by 7 days time!!! eek.

Just want to chime in, after much searching eventually I came across the library, Imageadjuster (http://www.davebollinger.com/works/imageadjuster/)

Which performs such image adjusting with ludicrous ease.

However, if anyone wants to answer my questions (the HSB/RGB thing, and any other methods of doing this) for the sake of improving my wisdom, feel absolutely free. Smiley

many thanks
