Here we generalize the binary definition of texture to apply to arbitrary grayscale images, allowing us to map grayscale textures to the same 10-dimensional space defined in the binary case. We show that the grayscale construction reduces to the binary case for binary images and study the distribution of natural images using the generalized definition. We check whether the natural statistics of grayscale images can predict the salience of binary and ternary textures as measured by psychophysical experiments. Finally, we discuss possible extensions of the model, including measuring the texture statistics at several different scales.
