Using a Data-bearing Frame to Capture an Extended Target
  DOI :  10.2352/ISSN.2470-1173.2016.20.COLOR-324  Published OnlineFebruary 2016

A system for the automatic detection of the entirety of an arbitrary image target is described. This is achieved by surrounding the target image with a data-bearing halftone or "StegaFrame" and by a camera-based detection system that can efficiently find the StegaFrame by means of judiciously placed detection windows. The frequency-domain-based detection scheme is fast and provides the added advantage of estimating scale and orientation of the desired content. An intuitive user interface guides the user until a successful detection is achieved. This approach is demonstrated in an application to locate and analyze a color chart for the purpose of calibrating a mobile device to be able to measure skin tone. An identifier to access print-run specific colorimetry data, along with other data for client analytics is embedded in the data-bearing border. The design of the detection system is optimized through exhaustive simulation. Experimental results confirm that the automated scheme, implemented on a mobile phone, performs as well as costly dedicated colorimetric hardware.
