History
dswitkin 01eed5266e - Converted parts of the PDF 417 reader to use BitMatrix. 
- Changed the PDF 417 detector to search the image more broadly, instead of assuming the barcode starts in the left 1/4 and ends in the right 1/4. We now get 8/23 on the real-world blackbox test, and we'll probably do even better with further improvements here.
- Added a quiet zone to two of the unit test images and updated a golden result for one of them. We now get 3/7 on the first test.
- Tried to fix some bugs in the upside down code but it still doesn't work.

code39-1 More updates to use local test images rather than remote 2008-06-16 16:13:12 +00:00
code39-2 More updates to use local test images rather than remote 2008-06-16 16:13:12 +00:00
code39-3 Added 17 real world Code 39 images to our unit tests. We decode all 17, upside down and right-side up. 2008-06-20 19:20:27 +00:00
code128-1 More updates to use local test images rather than remote 2008-06-16 16:13:12 +00:00
code128-2 Recent bug fix uncovered some bugs in test case -- fixing those 2008-10-01 16:17:03 +00:00
code128-3 Finally actually fix the Code-128 bug and add tests 2008-09-24 12:16:41 +00:00
datamatrix-1 Added code for the Data Matrix decoder. 2008-03-11 03:48:12 +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
ean8-1 First set of updates to use local test images rather than remote 2008-06-16 16:00:51 +00:00
ean13-1 Added 13 new blackbox images. 2008-10-07 18:57:15 +00:00
ean13-2 Adding a few test images from a defunct issue report 2009-04-28 22:29:30 +00:00
ean13-3 Added 55 EAN-13 real world test images. For mobile we get 49/55 of these, 55/55 with try harder. 2008-08-08 15:26:21 +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
falsepositives Reworked the false positives unit tests to track each rotation separately, and to allow new tests to be added. I also removed four images which are going to live in another test. 2008-06-25 00:51:37 +00:00
itf-1 Moved one file back to the ITF directory because it should be readable. 2008-12-23 17:21:31 +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
partial Moved one file back to the ITF directory because it should be readable. 2008-12-23 17:21:31 +00:00
pdf417 - Converted parts of the PDF 417 reader to use BitMatrix. 2009-06-30 21:55:19 +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-1 Disallow BufferedImage of type TYPE_CUSTOM -- not decoding properly, and is kind of a weird case from ImageIO anyway 2008-03-03 22:45:52 +00:00
qrcode-2 Fixed a typo in our golden results. 2009-05-21 20:29:56 +00:00
qrcode-3 Added a new unit test of real world QR codes. We get 29/42 - pretty good, but room for improvement. 2008-08-25 17:44:23 +00:00
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
unsupported Added new test of unsupported barcodes, to make sure we don't decode them. 2008-06-25 01:26:22 +00:00
upca-1 Added BarcodeFormat to Result, indicating what type of barcode was detected. Added TRY_HARDER hint. Improved logicalness of results when reading UPC-A code / EAN-13 code starting with 0. 2008-02-25 23:02:50 +00:00
upca-2 Added 52 real world UPC-A greyscale test images. We get 26/52, but more with try harder. I think I'm going to break try harder results into their own test so we can track these separately. 2008-07-09 19:00:33 +00:00
upca-3 Added some very difficult reflective UPC-A images - we get 8/21. We would probably have to do something very special to handle soda cans with those silver on silver barcodes. 2008-07-09 20:50:03 +00:00
upca-4 Added 13 new blackbox images. 2008-10-07 18:57:15 +00:00
upce-1 First set of updates to use local test images rather than remote 2008-06-16 16:00:51 +00:00
upce-2 Added 41 real world UPC-E tests. We need to improve regular decoding here: it gets 17/41, but try harder gets 28/41. 2008-07-09 21:37:09 +00:00
upce-3 Added a reflective UPC-E unit test. We cannot decode any of these silver on silver barcodes. 2008-07-09 21:46:27 +00:00
