1. A system, comprising: at least one processor; and memory including instructions that, when executed by the at least one processor, cause the system to: receive an image acquired using a camera of a portable computing device, the image including a representation of an object of interest for a user of the portable computing device; analyze at least a portion of the image using at least one feature detection process to identify a set of feature points corresponding to the representation of the object of interest; identify, based on a subset of the set of feature points, a scalar element represented in the image, the scalar element corresponding to a visual element associated with one or more types of objects; determine, based at least in part upon the scalar element, an object classification for the object of interest; determine a set of ratios representative of objects in the object classification; analyze distances between pairs of feature points of the set of feature points to determine values for ratios of the set of ratios, at least a subset of the set of ratios including dimensions of the scalar element with respect to dimensions of the object of interest; compare the values for the ratios against ratio data stored for objects in the object classification; determine a matching object where the values for the ratios correspond to the ratio data for the matching object with at least a minimum confidence; and provide information for the matching object to the portable computing device.
