Initial import of tesseract-1.04b from pkgsrc-wip (packaged by heinz@ and myself): This code is a raw OCR engine. It has NO PAGE LAYOUT ANALYSIS, NO OUTPUT FORMATTING, and NO UI. It can only process an image of a single column and create text from it. It can detect fixed pitch vs proportional text. Having said that, in 1995, this engine was in the top 3 in terms of character accuracy, and it compiles and runs on both Linux and Windows. Another current limitation is that it only recognizes English and its character set is only US-ASCII. Training code IS included in the open source release however, and will be included in a future release.

Update graphics/tesseract to 3.04.01. Move to new home at Github. Clean up. 2015-02-17 - V3.04.01 - Added OSD renderer for psm 0. Works for single page and multi-page images. - Improve tesstrain.sh script. - Simplify build and run of ScrollView. - Improved PDF output for OS X Preview utility. - INCOMPATIBLE fix to hOCR line height information - commit 134ebc3. - Added option to build Tesseract without Cube OCR engine (-DNO_CUBE_BUILD). - Enable OpenMP support. - Many bug fixes. 2015-07-11 - V3.04.00 - Tesseract development is now done with Git and hosted at github.com (Previously we used Subversion as a VCS and code.google.com for hosting). - Tesseract now requires leptonica 1.71 or a higher version. - Removed official support for VS 2008. - Added support for 39 additional scripts/languages, including: amh, asm, aze_cyrl, bod, bos, ceb, cym, dzo, fas, gle, guj, hat, iku, jav, kat, kat_old, kaz, khm, kir, kur, lao, lat, mar, mya, nep, ori, pan, pus, san, sin, srp_latn, syr, tgk, tir, uig, urd, uzb, uzb_cyrl, yid - Major updates to training system as a result of extensive testing on 100 languages. - New training data for over 100 languages - Improved performance with PIC compilation option. - Significant change to invisible font system in pdf output to improve correctness and compatibility with external programs, particularly ghostscript. - Improved font identification. - Major change to improve layout analysis for heavily diacritic languages: Thai, Vietnamese, Kannada, Telugu etc. - Fixed problems with shifted baselines so recognition can recover from layout analysis errors. - Major refactor to improve speed on difficult images, especially when running a heap checker. - Moved params from global in page layout to tesseractclass. - Improved single column layout analysis. - Allow ocr output to multiple formats using tesseract command line executable. - Fixed issues with mixed eng+ara scripts. - Improved script consistency in numbers. - Major refactor of control.cpp to enable line recognition. - Added tesstrain.sh - a master training script. - Added ability to text2image training tool to just list available fonts. - Added ability to text2image to underline words. - Improved efficiency of image processing for PDF output. - Added parameter description for each parameter listed with 'print-parameters' command line option. - Added font info to hOCR output. - Enabled streaming input and output of multi-page documents. - Many bug fixes. 2014-02-04 - V3.03(rc1) - Added new training tool text2image to generate box/tif file pairs from text and truetype fonts. - Added support for PDF output with searchable text. - Removed entire IMAGE class and all code in image directory. - Tesseract executable: support for output to stdout; limited support for one page images from stdin (especially on Windows) - Added Renderer to API to allow document-level processing and output of document formats, like hOCR, PDF. - Major refactor of word-level recognition, beam search, eliminating dead code. - Refactored classifier to make it easier to add new ones. - Generalized feature extractor to allow feature extraction from greyscale. - Improved sub/superscript treatment. - Improved baseline fit. - Added set_unicharset_properties to training tools. - Many bug fixes. - More training source data included.
