hello guys consider that i have an rgb image taken from a camera by

byte[] raw = videoControl.getSnapshot(null);
Image image = Image.createImage(raw, 0, raw.length);
now i want to analyze pixel by pixel to see if the color of any pixel corresponds to skin color or not... well i wont ask u to get the exact value of skin color.... can anybody just tell me how to scan each pixel to see if its of a particular color that i want....and if it is i want to replace it wil another color... what should i do to get this result????
