Abstract
Introduction: Studies of object perception are hampered by the difficulty of
mathematically describing the similarity of realistic images. Recently, color based metrics
have been developed to search for similar images in large databases of realistic images.
Such metrics have been shown to predict human subjects' similarity rankings of realistic
images, because the color of realistic images often depends on their content. Can color
similarity metrics also predict perceptual similarity of realistic images to nonhuman
primates?
Methods: The color similarity metric used was the Earth Mover Distance (EMD, Y. Rubner,
