A quantitative evaluation of the conceptual consistency of visual words and visual vocabularies ?

There are more visually distinct patterns than can be listed in a codebook. One element of a codebook represents a set of many, visually distinct patterns. There are no single, selective SIFT descriptors to serve as codebook elements.
