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.

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.

dswitkin f5124cec37 Created a new blackbox unit test of real-world PDF 417 images taken with an Android device. Currently we decode 0/23.

dswitkin 2397216901 Added a few computer-generated PDF 417 barcodes to the blackbox tests. The current code doesn't seem to handle more advanced error correction modes.

dswitkin eb8b9677cf Added the previous Android benchmark I've been using to track performance, as well as a new one which uses wider images and therefore twice as many pixels.

dswitkin 1da9bd60b3 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. 
Also made the ImageConverter app ignore some kinds of files.

dswitkin c07fad6410 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.

dswitkin dfb6b60dd4 - Added a new unit test of 13 ITF images I took with a T-Mobile G1. 
- Added upside down unit tests for the existing ITF images.
- Removed the temporary format code from these tests now that ITF is on by default.

dswitkin c3564411fb 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.

dswitkin 0f648cd1be Ported and rewrote the Renderer unit test to test QRCodeWriter. We encode several barcodes looking for good behavior, and several others which are compared pixel by pixel to golden results stored in PNGs. I'm happy to say we nail the three images Satoru created to the dot! 
Along the way, I added support for encoder hints, and no longer hardcode the error correction level.

dswitkin edcf34f0c5 Created 40 new blackbox images which are partial shots of a very large QR code. In mobile mode we do OK, but in try harder we find bogus 1D results in almost half of these. I'm checking this in as a baseline, and will work on improving the situation in a subsequent change.

dswitkin f05d22687e 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.

dswitkin 4d1229bd65 Created a library of images which do not contain barcodes, or contain barcodes we don't yet support. Wrote a new unit test designed to identify false positives, and set a benchmark which we can improve over time. Out of these 26 images, tested in all four rotations, we currently find 44/104 false positives. The Code 39 decoder in particular seems to be too lenient.
