Luminance Blender

The Luminance Blender pre-processing block computes the luminance, or grayscale, part of the color image. As some image analysis processes are more efficiently when executed on grayscale images, the luminance data can be transferred to the host memory with the color data.

The formula for the luminance blender is:

Y = (0.299 x R) + (0.587 x G) + (0.114 x B)

Note. The Luminance Blender has no MultiCam parameters because the algorithm uses fixed coefficients.
