Fig 7. Classifier performance as a function of number of image properties.

Fig 7

Image properties were first ranked by their individual d’ measures and then adding in order from highest to lowest. The reference classifier (in grey) only integrates luminance properties, while +ΔL/M adds the ΔL/M measures, +ΔS/(L+M) adds the ΔS/(L+M) measures and +ΔL/M+ΔS/(L+M) adds both color measures. Intervals correspond to lower and upper 95th percentile confidence interval based on parametric bootstrap simulations (n = 1000).
