Abstract
To identify an image characteristic, a tree structured code having coding representing each of a plurality of training images is stored in a memory. Coding representing a sample image, not included in the plurality of training images, is compared to the tree structured code to identify the training image coding in the structured tree code closest to the sample image coding. A characteristic of the sample image is identified based upon the training image represented by the closest training image coding.
