2019-04-18Put edge in middle of window slice, rather than at left side, and gofmtNick White
2019-04-18Add basic cleanup tool; working, but more refinements planned.Nick White
This uses integral image calculations, so they have been exported in the binarization package
2019-04-17Add basic dehyphenate toolNick White
2019-03-28Remove todo for integral image testing for nowNick White
2019-03-28Improve tests; test regular sauvola, and add option to update golden filesNick White
2019-03-26Add zeroinv option for binarize commandNick White
2019-03-26Move sauvola binarization tool to cmd/binarizeNick White

2019-01-30Set window size automatically based on resolutionNick White
2019-01-30Remove dependency on Imger packageNick White
2019-01-30Add integral image functionality to enable massive speedup of SauvolaNick White
Note that there are some very small differences to the output compared to the basic algorithm, but this doesn't make much difference. This is due to minor differences with the standard deviation calculation throughout, and with mean calculation at edges, for reasons I'm unclear about. WIP integral image speedup. mean is working Very WIP, but mean is perfect once full window is used Integral version all working! Remove debugging info Organise code better
2019-01-29Switch binarization to Sauvola algorithmNick White
2019-01-25Simplify writing of sort functions in line pkgNick White
2019-01-25gofmtNick White
2019-01-25Use consistent naming for .prob and .hocr OcrNameNick White

2019-01-24Better separation between library and toolNick White
2019-01-24Merge bucket-lines-{prob,hocr} into one tool called bucket-lines, that uses ↵Nick White
the filename extension to determine how to process the lines
2019-01-24Add -d to -hocr tool, and improve documentationNick White
2019-01-24Rename ocropus bucket tool, add -d option, and improve documentationNick White
2019-01-24Simplify .prob processingNick White
2019-01-24Get -tess tool to use generic bucket functions too. things are in pretty ↵Nick White
good shape now, just a few small todos left
2019-01-23Track and print bucket stats genericallyNick White
2019-01-23Create general BucketUp function, use it for line-conf-bucketsNick White
2019-01-23Update line-conf-buckets to mostly use package functions too.Nick White
Working now, but needs more consolidation to be worth it.
2019-01-23Separate out hocr parts from line partsNick White
2019-01-23Move image copying out to an interface function, so I can share code with ↵Nick White

to do, see TODO in hocr.go

2019-01-19line-conf-buckets-tess is done now. could do with cleaning up, but seems to ↵Nick White
be working well
