KanjiTomo OCR is a Java library for identifying Japanese characters from images. The algorithm used in this library is custom made, originally used with KanjiTomo program:https://www.kanjitomo.net/ Description of the algorithmis here.

This library is intented to be used with interactive programs where user can point to individual words with a mouse. Batch-processing whole pages is not supported.

• IncludeKanjiTomoOCR.jar to your project
• Add "--illegal-access=deny" JVM parameter, this is not strictly required but prevents unnecessary warnings on startup
• "-Xmx1200m" and "-server" JVM parameters are also recommended for performance reasons

• CreateKanjiTomo class instance
• Load data structures withloadData method. This needs to be done only at startup.
• Set the target image withsetTargetImage method. This can be whole page or screenshot around target word. Screenshots around mouse cursor can be taken with Java'sRobot class.
• Start OCR withrunOCR method. Point argument determines the first character to be scanned in target image's coordinates and should correspond to mouse cursor location.
• Results are returned asOCRResults object.bestMatchingCharacters field contains a list of identified characters andwords list contains results of a dictionary search from these characters.

KanjiTomotomo =newKanjiTomo();tomo.loadData();BufferedImageimage =ImageIO.read(newFile("file.png"));tomo.setTargetImage(image);OCRResultsresults =tomo.runOCR(newPoint(80,40));System.out.println(results);
