Introduction

• RGB
  • consistent with camera output
  • no transformation
  • sensitive to intensity inhomogeneities

• Lab and Luv
  • perceptually uniform
  • nonlinear transformation
  • a,b and u,v are unstable when intensity is small

• IHS
  • intuitive with regard to human perception
  • nonlinear transformation for H,S
  • S is unstable when I is small
  • H is unstable when I and S are small

• I1I2I3 (experimentally defined by Ohta et al.)
  • linear transformation
  • intuitive with regard to human perception
