Claim:
A method comprising: pointing a portable image sensor device towards a physical object that is free of visible digital encoding; capturing one or more 2D frames of imagery from the physical object using the sensor device; providing image information representing the object to a processing device, and receiving first data derived from said provided image information from the processing device; using the first data to identify corresponding second data in a data structure that stores plural second data, where the data structure associates the plural second data with plural different first data; and though use of the second data identified from the data structure, initiating an action relating to the physical object from which the imagery was captured; wherein the method further includes analyzing the imagery for one or more clues, the clue(s) helping the first data to better correspond to a particular object, rather than to another object or to visual clutter within the imagery, the analyzing including one or more of the following: i. regarding a point at a center of an image frame as corresponding to the particular physical object, and from that point analyzing to discern an associated boundary; ii. identifying features in the imagery having a relatively greater movement between frames of imagery, as contrasted with other image features; iii. identifying plural non-parallel straight edge boundaries in the imagery; iv. identifying a trapezoidal shape in the imagery; v. identifying an object within the imagery by reference, at least in part, to color; and vi. identifying an object within the imagery by reference, at least in part, to spatial frequency.
