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 5e752acd25 Added a new feature to the test app, which captures all the device info and default camera parameters, then bundles them up into an email. This will make it very easy to get some important info about new devices from users (e.g. the HTC Hero which I don't have). 
Also did a lot of other cleanup, added an about box, and prepared the app to be released on the Market.

dswitkin d71c099313 Converted the Android client and the test app to use the Android 1.5 SDK, and to use a more efficient preview frame mechanism too. We now require devices to be running Cupcake or a newer version of the platform. This change temporarily removes the Proguard step, which Sean is going to add back.

dswitkin 167197ec7a Refactored the MonochromeBitmapSource class hierarchy into LuminanceSource, Binarizer, and BinaryBitmap classes. The unit tests pass and I believe the change is complete, but there are some clients like J2ME and Bug that I can't build. 
This change will allow new thresholding algorithms to be developed and tested, as well as implemented per platform if needed (e.g. in JNI on Android). It should also perform better when multiple 2D Readers are installed, because the underlying image will only be converted to 1 bit once. It also allows some platforms to return luminance data without a copy.

The current state of this checkin is to use the old black point algorithm, which now lives in GlobalHistogramBinarizer. This will be our benchmark and fallback for slower platforms. Going forward we will begin to use LocalBlockBinarizer as I shake out the edge cases and tune it for performance. Currently it is unused.

IMPORTANT: I have temporarily included three methods from MonochromeBitmapSource at the end of BinaryBitmap as a way to make this change in stages. They are deprecated and will be removed soon. All of the Reader classes will need to change the way they examine 1 bit pixels to use the new getBlackRow() and getBlackMatrix() calls.

dswitkin e19e9a83f6 I moved a chunk of the histogram/black point code out of BaseMonochromeBitmapSource and into BlackPointEstimator which makes a lot more sense. Unfortunately I had to expose three new methods and touch a bunch of files. But I did manage to reuse an array on subsequent calls, which was being allocated on every row scanned, so that might be a bit faster. It will also be easier to convert this code to JNI in the future if we want to, and/or do more advanced thresholding.

dswitkin f21c34ae16 First pass at adding a UI for sharing data via QR Codes. There's now a Share button in the main capture menu which leads to a choice of contacts, bookmarks, and clipboard contents, which will be encoded and shown full screen. Launching the bookmarks picker currently crashes with a permission problem, which I'm investigating.

dswitkin 8671371c59 Did a big refactoring on the MonochromeBitmapSource. I removed all the caching luminance calls and converted them to getting luminance data on demand. This saved another 33,000 function calls per rejected scan, good for another 15 ms savings. I also moved the luminance calls to BaseMonochromeBitmapSource and made them protected, to indicate that the decoders shouldn't use them. 
Overall the recent optimizations took one rejected scan from 307 to 135 ms, which is definitely noticeable.

WARNING: I am not able to build the Bug or J2ME clients, but I believe they are correct.

dswitkin 43e155804f Looks like -allowaccessmodification to ProGuard results in a bogus binary. It compiles, but the Dalvik verifier rejects it at runtime. I'm removing this flag for now, which means we lose inlining on some important getters and setters.

dswitkin 1e478df248 Added androidtest to the top-level clean target and set it up for ProGuard too. Made both Android builds depend on clean so they work when switching between normal and ProGuard builds, and made install and reinstall use the latest binary instead of recompiling.

dswitkin de419268b8 Wrote a benchmark activity for Android which reads images recursively from the SD card, decodes each 10 times, and prints the average time to decode in milliseconds. The UI is extremely minimal, as the results are written to the log, but this is a good start towards measuring our performance under Dalvik on a platform without floating point hardware. This should run fine on the emulator but I haven't tested it yet.

dswitkin 15deb0c3d9 Checked in the ZXing Test app for Android under androidtest. This application exercises all the intents we support including scanning, encoding, and searching books. It also has a special camera mode which saves greyscale images to the SD card which I use to generate blackbox images.
