RGBQ: 3-Channel Color Superiority
Following up on the previous article and training with both 4 and 3-channel implementations, I recommend the following:
RGB(255, 255, 255)
π΄ Red photon energy: 1.77 eV (~700nm)
π’ Green photon energy: 2.25 eV (~550nm)
π΅ Blue photon energy: 2.76 eV (~450nm)
βͺ White light energy flux: 1728.9 eV
Red scale: 1.77 eV / 1728.9 eV = 0.001024
Green scale: 2.25 eV / 1728.9 eV = 0.001301
Blue scale: 2.76 eV / 1728.9 eV = 0.001596
RGBQ(R*red_scale, G*green_scale, B*blue_scale)
All channels are unique providing different gradient advatages to the network, physically meaningful as the approximate photon energy flux from each channel (analogous to photons exposing film), and the sum of the channels provides a very nice grayscale image. With this system, max(R) = 0.261062, max(G) = 0.331858, and max(B) = 0.407080 such that the channels sum to 1.000 for white light. Don't round the scaling factors (as done above). Godspeed.
