cbrTekStraktor is an application to automatically extract text from the text bubbles or speech balloons present in comic book reader files (CBR). Its prime goal is to perform analysis on the texts of comic books. cbrTekStraktor can however also be used for scanlation or similar purposes. The application also enables to manually define text areas in CBR files. The application comprises a simple graphical editor for further processing the extracted text. The text extraction is achieved by a combination of statistical and graphical processing operations. It is based on the following 3 major algorithms - Binarization of color images (Niblak and other methods) - Connected components - K-Means clustering Apache Tesseract is used to perform Optical Character Recognition on the extracted text. A subsequent version of the application will integrate with translation software in order to provide automated translation of comic book texts and re-inserion of translated texts

The DjVu Reference Library 3.5 was released by Lizardtech under the GNU General Public License version 2. DjVuLibre-3.5 was developed by Leon Bottou and others as a "Derived Work" of the DjVu Reference Library 3.5. As such, it is also subject to the GNU General Public License version 2. Several patents apply to two very specific aspects of DjVu and DjVuLibre. The patents cover a particular aspect of the ZP-coder (the arithmetic coder used in DjVu and implemented in libdjvu/ZPCodec.cpp) and the background masking technique used in the IW44 wavelet encoder (implemented in libdjvu/IW44EncodeCodec.cpp). Most patents are owned by AT&T. LizardTech has very broad rights to them and grants free and permanent licenses to them for the purpose of building GPL software with the DjVu Reference Library. The grant is materialized by two paragraphs in the headers of the DjVu Reference Library source files. Lizardtech also published an official statement about the open source.
