This chapter is about light itself and our perception of light in terms of brightness and color. The chapter covers:

  • light in terms of electro-magnetic radiation and mixtures of light as continuous spectra
  • a brief introduction to colorimetry, the science of color perception, human trichromatic color perception and how colors can be represented in various color spaces.
  • a number of advanced topics such as color constancy, gamma correction, and an example concerned with distinguishing different colored objects in an image.
