RGB of Y pixels...???... - Khubaib - Dec 11 2:51:00 2002

Dear members..I have a question...if i have only Y pixels of an image ( no U and V pixels), then what is the way to get the corresponding R, G and B componenets... ( the problem is that i have a Y pixel file of an image and i want to get its R, G and B equivalent)... regards, Khubaib |

To be more clear ... The resulting RGB will produce a B&W image only! Colors (RGB) are produced by a weighted sum of the Luminance (Y) and Chrominance (Cr Cb) values. Since you only have Luminance values you will only produce a black and white image. -----Original Message----- From: Jean-Michel MERCIER [mailto:] Sent: Thursday, December 12, 2002 5:22 AM To: Subject: RE: [imagedsp] RGB of Y pixels...???...
