History

dswitkin 5cc1df3c92 Finished work on the local binarizer and renamed it to HybridBinarizer. It uses the old histogram for 1D and the new approach for 2D. The unit tests don't fully demonstrate how much better this is in real-world lighting, but it pretty much solves the situation of pointing at a QR Code for 30 seconds without scanning, due to a shadow or gradient. HybridBinarizer is now the default across all the fast clients and the unit tests. git-svn-id: https://zxing.googlecode.com/svn/trunk@1157 59b500cc-1b3d-0410-9834-0bbf25fbcc57		2009-12-13 21:08:57 +00:00

datamatrix-2	Added 18 real world DataMatrix blackbox images, plus turned on rotation for the original set.	2009-01-06 21:11:55 +00:00

ean13-4	Added a new blackbox test with extreme shadows and highlights. We do pretty poorly on this, but I've been experimenting with local thresholding algorithms which are a night and day improvement.	2009-06-16 18:47:34 +00:00

itf-2	- Added a new unit test of 13 ITF images I took with a T-Mobile G1.	2009-03-09 20:48:48 +00:00

pdf417-2	Created a new blackbox unit test of real-world PDF 417 images taken with an Android device. Currently we decode 0/23.	2009-06-30 18:47:34 +00:00

qrcode-3
qrcode-4	Added a new QR Code unit test of real world photos of t-shirts. These are notoriously difficult because the barcodes don't lie completely flat. We're able to decode 33/48 which is better than I thought, although most of the images which fail look within reach.	2008-11-26 16:39:34 +00:00
qrcode-5	Created a new QR blackbox test with difficult exposures, mostly self-shadowing cases. We only get 34 out of 120 tests, which is about what I expected. To fix these we will have to move away from a global black point and towards a more sophisticated local thresholding algorithm.	2009-05-28 18:45:48 +00:00
