Measurements or models of a human body are generated. An image of the human body may be identified and a fiducial map may be generated. The fiducial map may be compared to pre-processed fiducial maps stored in a data store. A plurality of pre-processed fiducial maps of human bodies may be identified when a correlation between the fiducial map and the pre-processed fiducial maps exceeds a defined threshold. A silhouette image of the human body may be generated based on the image and may be compared to pre-processed silhouette images associated with the plurality of pre-processed fiducial maps. One of the pre-processed silhouette images may be identified when a correlation value between the silhouette image and the pre-processed silhouette images exceeds a defined threshold. Measurements or a model of the human body may be identified based on the one of the pre-processed silhouette images.
