Function Documentation

Image<float> computeLuminance

(

const Image< PixRGB< byte > > &

img

)

Compute the luminance of an RGB image, and convert from byte to float pixels.

note that we could as well use luminance() defined in Image/ColorOps.H except that the rounding side effects are slightly different. This function corresponds to the one we use in our master code (it's burried in Channels/InputFrame.C).
