RGB :

Output image, which has the same size as YCC and type of double.

Description

ycbcr2rgb convert a RGB image to the equivalent YCbCr image using:

R = Y + 1.403*(Cr - 0.5)

G = Y - 0.344*(Cr - 0.5) - 0.714*(Cb - 0.5)

B = Y + 1.773*(Cb - 0.5)

Examples

RGB = imread(fullpath(getIPCVpath() + "/images/baboon.png"));
YCC = rgb2ycbcr(RGB);
RGB = ycbcr2rgb(YCC);
