Figure 6.

Images could be categorized as animate versus inanimate using only the average color of the object in each image. (A) Chromaticity coordinates for the 92 images used by Kriegestkorte et al. (2008). The asterisks show the neutral point of the color space. The blue circles are the average u′ v′ value of all the color values plotted in the figure. (B) A support vector machine with a radial basis function trained on only the average CIE u′ v′ of the object in each image categorized animate images at an accuracy of 91.67% and inanimate images at an accuracy of 70.45%. Inset shows the chromaticity coordinates for all images as in A, in which open symbols indicate images classified as “animate” and filled symbols indicated images classified as “inanimate”.
