tesseract-ocr - Tesseract command line OCR tool (devel)
PPA description
This PPA contains an OCR engine - libtesseract and a command line program - tesseract. The development version available here (currntly 5.0.0 ) is better in many aspects (functionality, speed, stability) but is not 100 % API compatible with version 4.0. Tesseract 4 added a new neural net (LSTM) based OCR engine which is focused on line recognition, but also still supports the legacy Tesseract OCR engine of Tesseract 3 which works by recognizing character patterns. Compatibility with Tesseract 3 is enabled by using the Legacy OCR Engine mode (--oem 0). It also needs traineddata files which support the legacy engine, for example those from the tessdata repository. Tesseract has unicode (UTF-8) support, and can recognize more than 100 languages "out of the box". Tesseract supports various output formats: plain text, hOCR (HTML), PDF, invisible-text-only PDF, TSV. The master branch also has experimental support for ALTO (XML) output.
