Abstract :
We introduce a class of metric perceptual distances between textures. The first metric is sensitive to both rotation and scale differences, and provides a basis for two other metrics, one invariant to rotation, and the other invariant to both rotation and scale. Our metrics are based on Earth Mover´s Distance computations on log-polar distributions of spatial frequency computed from Gabor filters. We show consistency of our metrics with psychophysical findings on texture discrimination and classification
