Description

G06K encompasses technologies for reading, interpreting, and displaying graphical data, along with the physical media and mechanisms for storing and handling recorded information. This subclass covers optical character recognition (OCR), bar code and QR code reading, image processing for data extraction, and display systems for presenting visual information. It also includes mechanical and electronic systems for handling physical record carriers such as magnetic tapes, optical discs, and card readers. Adjacent subclasses address pure image processing (G06T) and specialized computing architectures (G06F), whereas G06K focuses specifically on the interface between graphical/recorded data and computational systems.
