RGB2YUV
Converts RGB images
to the YUV color model.
void iplRGB2YUV(IplImage* rgbImage , IplImage* yuvImage );
rgbImage ThesourceRGBimage.
yuvImage The resultant YUV image.
Discussion
The function converts the RGB image rgbImage to the YUV image
yuvImage according to the following formulas:
Y =0.3
·R + 0.6·G + 0.1·B
U = B
- Y
V = R
- Y.
The function checks that the input image is an RGB image; it sets the
channel sequence and color model of the output image to YUV.
YUV2RGB
Converts YUV images to
the RGB color model.
void iplYUV2RGB(IplImage* yuvImage , IplImage* rgbImage );
yuvImage The source YUV image.
rgbImage The resultant RGB image.
Discussion
The function converts the YUV image yuvImage to the RGB image
yuvImage . The function checks that the input image is an YUV image and
that the output image is RGB.
