1. A computerized object recognition scene trait analysis system for enhancing identification of objects in a scene capture, the scene capture comprising (i) a digital representation of an image capture of a scene by an image sensor and (ii) one or more scene trait values captured by one or more scene trait sensors at the time of the image capture; the system comprising: a scene variance analyzer comprising one or more computers configured to: compute scene trait variances, the scene trait variances corresponding to variances of scene trait values across a plurality of scene captures; and determine distinguishing scene traits based on scene trait variances that are above a threshold value; and a weight processor comprising one or more computers configured to, for each of a plurality of scene captures: determine relative weighting for the distinguishing scene traits; and generate metadata using the relative weighting; wherein the system is configured to associate generated metadata corresponding to a particular scene capture with features derived from a digital representation corresponding to the particular scene capture.
