1. A method in a mobile computing device, the method comprising:
controlling a camera to capture an image;
tracking, in association with the image, a pose of the mobile computing device in a coordinate system;
detecting a region of interest (ROIs) depicting an item in the image;
determining a location of the ROI in the coordinate system, based on the tracked pose;
obtaining an item identifier corresponding to the ROI by (i) when a previously recognized item identifier is not available, executing a recognition mechanism to derive the item identifier from the ROI, and (ii) when the previously recognized item identifier is available, bypassing the recognition mechanism and retrieving the previously recognized item identifier; and
returning the obtained item identifier corresponding to the ROI.
