O Clara OCR - http://www.claraocr.org - é um software para reconhecimento de caracteres desenvolvido por Ricardo Ueda Karpischeck, que tem como caracteristica rodar nos varios sabores do Unix, desde que usem X windows e suportem C.

A seguir incluo um pequeno trecho do FAQ encontrado no website do projeto. Não deixe também de visitar o website.

  Clara differs from other OCR softwares in various aspects: 
  
  1. Most known OCRs are non-free and Clara is free. Clara focus the X windows 
  system. Clara offers batch processing, a web interface and supports 
  cooperative revision effort. 
  
  2. Most OCR softwares focus omnifont technology disregarding training. Clara 
  does not implement omnifont techniques and concentrate on building 
  specialized fonts (some day in the future, however, maybe we'll try 
  classification techniques that do not require training). 
  
  3. Most OCR softwares make the revision of the recognized text a process 
  totally separated from the recognition. Clara pragmatically joins the two 
  processes, and makes training and revision parts of one same thing. In fact, 
  the OCR model implemented by Clara is an interactive effort where the usage 
  of the heuristics alternates with revision and fine-tuning of the OCR, guided 
  by the user experience and feeling. 
  
  4. Clara allows to enter the transliteration of each pattern using an 
  interface that displays a graphic cursor directly over the image of the 
  scanned page, and builds and maintains a mapping between graphic symbols and 
  their transliterations on the OCR output. This is a potentially useful 
  mechanism for documentation systems, and a valuable tool for typists and 
  reviewers. In fact, Clara OCR may be seen as a productivity tool for typists. 
  
  5. Most OCR softwares are integrated to scanning tools offerring to the user 
  an unified interface to execute all steps from scanning to recognition. Clara 
  does not offer one such integrated interface, so you need a separate software 
  (e.g. SANE) to perform scanning. 
  
  6. Most OCR softwares expect the input to be a graphic file encoded in tiff 
  or other formats. Clara supports only raw PBM.
