1. A method of generating a metric-based recognition map comprising: receiving, by a computing device configured to operate as an image processing engine, image data; compiling, by the image processing engine, an initial object-specific metric map for a specific human person from at least a portion of the image data where the portion represents at least a portion of the object; generating, by the image processing engine, a metric-based descriptor set by executing an image analysis algorithm on the portion of the image data as a function of the initial object-specific metric map; and storing the metric-based descriptor set in an object recognition database.
