Abstract
Representing an image includes extracting several types of information about an image that are then used to compute a joint histogram. A weighting factor may be applied to at least one of the types of information extracted about the image such that the joint histogram represents a weighted joint histogram. Representing an image may further include calculating a posterized joint histogram. The posterized joint histogram may be calculated after the weighting factor has been applied.
