1. A method of classifying an unknown material using texture, comprising: accessing a database of predetermined images each of a known material and each captured at a magnification factor that is relatively high; receiving a query image of the unknown material captured at a second magnification factor that is relatively lower than the magnification factors of the predetermined images; dynamically generating a collection of images of the known materials at the second magnification factor; matching the received query image against the dynamically generated collection of images; and classifying the unknown material in correspondence to a match between the received image and the dynamically generated collection of images.
