The weights to compute true luminance from linear red, green and blue are
these:
Y = 0.212671 * R + 0.715160 * G + 0.072169 * B
Conversion from Gray Scale to Color (Pseudo-color)
This section describes the conversion of gray scale image to pseudo color.
GrayToColor
Converts a gray scale to
color image.
void iplGrayToColor (IplImage* srcImage , IplImage*
dstImage, float FractR, float FractG, float FractB );
srcImage The source image. See Table 9-4 for a list of
valid source and resultant image
combinations.
dstImage The resultant image. See Table 9-4 for a list
of valid source and resultant image
combinations.
FractR,FractG,FractB The red, green and blue intensities for
image reconstruction. See Discussion for a
list of valid
FractR , FractG ,and FractB
values.
Discussion
The function iplGrayToColor() converts a gray scale source image
srcImage to a resultant pseudo-color image dstImage . Table 9-4 lists the
valid combinations of source and resultant image bit data types for
conversion from gray scale to color.
