----------------->>> HYPEROPIC BARCODE <<<----------------- =========================================================== >>>>>>>> SUMMARY <<<<<<<< This project aims to develop a first-class barcode scanner that can use the built-in iSight on modern iMacs and MacBooks, which suffer from a close-focus distance which is too far from the camera to provide a clear image of the barcode. Because of this farsightedness ("hyperopia"), existing solutions struggled or would not work at all. This decoder uses a mathematical simulator developed by Johann C. Rocholl for 1st generation iPhones which suffered from a similar problem. (See his thesis and original source code, enclosed.) It was updated to work with iSights by Michael LaMorte, Connie LaMorte, and Conor Dearden. Final debugging was contributed by Gwynne Raskind. Hyperopic Barcode is in use in products by Minder Softworks (www.mindersoftworks.com) and Bruji (www.bruji.com) >>>>>>>> THEORY OF OPERATION <<<<<<<< Video frames are passed to the decoder. If a barcode is thought to be found, the scanner line changes from red to orange and the digits are handed off to a method that scrapes Amazon for the lookup data. If no results are found, the scanner goes "tink" and the line goes back to red; if information is found, the scanner line momentarily changes to green and the scanner goes "ding". Because of the way the simulator works, it is possible that video frames that do not contain a barcode may generate a false barcode. For this reason, all suspected barcodes are sent to Amazon to verify their validity. >>>>>>>> IMPLEMENTING IN YOUR PROJECT <<<<<<<< 1) Add the Classes, Libraries, and Images folders to your project 2) In your target, add linker flags to all the libraries: -lopencv_core -lopencv_imgproc -lstdc++ -lz 3) In your target, add the following to the Header Search Path (with quotes): "$(SRCROOT)/Libraries" and make recursive 4) In your target, add the following to the Library Search Path (with quotes): "$(SRCROOT)/Libraries" and make recursive >>>>>>>> LICENSE <<<<<<<< Hyperopic Barcode is released under the 3-clause BSD License as follows: ----------------------------------------------------------------------------------------- (c) Copyright 2012 Conor Dearden & Michael LaMorte Portions (c) Copyright 2008-2009 Johann C.
