7. A system for enabling retrieval of a collection of captured images that form at least a portion of a library of images, the system comprising: an image analysis module that operates to: receive images for the library, the images being captured by one or more consumer-level users that operate corresponding image capturing devices; detect whether individual images depict persons; normalize the individual images for lighting and pose of the depicted persons using at least one of a histogram or linear ramp intensity analysis; perform recognition on the normalized images to determine recognition information for the depicted persons, the recognition information including information about a clothing or apparel of the detected one or more persons; use a probabilistic model and the recognition information to determine an identity assignment for the one or more persons in the captured image, wherein the probabilistic model is based at least on a time when the image captured and the information about the clothing or apparel, wherein the identity assignment is determined according to a combination that includes at least the time information and the clothing or apparel information; an indexer that generates index data, wherein the index data associates the recognition information determined from the one or more persons depicted in the received images with a corresponding captured image that contained that person.
9. The system of claim 7 , wherein the image analysis module generates one or more modules are configured to generate recognition information for persons using one or more facial features of the person.
