OCRFeeder can also be run in pure command line mode: One can even make multiple separate entries with settings for each desired combination of language and application (and naming them like "Traditional Chinese - Tesseract", "German - Tesseract" and "German - CuneiForm", because we may want the same language to be recognized by different applications) to select them later from the pull down "OCR engines" list in the main OCRFeeder window. In case of Tesseract and CuneiForm one has to add "-l" switch followed with a proper language/script code (for example "-l pol" for Polish or "-l dan-frak" for Danish Fraktur) to the given engine's settings. Main OCRFeeder window allows to choose on the fly which engine to use for a particular area, there is also setting for making one engine the default choice.Īs of version 0.7.3 there is no easy way to choose a language of a recognized text. It is possible to add other engines and to change these options manually, there can be more than one engine entry using the same application. One has only to install in Ubuntu its OCR engines of choice - one or more - and then detect them in OCRFeeder settings. It has predefined settings for Tesseract, CuneiForm, GOCR and Ocrad, so the user doesn't need to know how to invoke them. It doesn't make character recognition itself, but uses other OCR apps (through so called "OCR engines" settings) instead. OCRFeeder suite provides handy GUI, which is basically a front-end for some image, OCR and text tools (like unpaper or spellchecker). While Tesseract and CuneiForm are the most accurate, under Linux now they lack graphical interface (GUI), which is a very important usability feature for a typical desktop user.
