G06V 30/12
Definition
Diese Klassifikationsstelle umfasst:(Für diese Definition ist die deutsche Übersetzung noch nicht abgeschlossen)
Processes and devices for detecting or correcting character recognition errors after image input. The errors can be detected or corrected automatically (e.g. by a computer program), with the help of an operator, or as a semi-automatic process (e.g. by displaying an image on a graphical user interface and requesting human intervention). Detecting errors in particular comprises evaluating the quality of given image or video data with regard to the suitability for being subjected to an automated character recognition process. Typical quality criteria include image sharpness/blurriness, resolution, contrast or brightness.
Monitoring print quality by performing character recognition on the prints, wherein quality relates to a property of the characters or of the digital ink insofar as its effect on the accuracy or performance of the character recognition process. Quality within the meaning of this group is a property of the characters or of the digital ink insofar as it has an effect on the accuracy or performance of the pattern recognition process.
Examples
Evaluation of the quality of recognition of the different fields of a bank cheque
Beziehungen zu anderen Klassifikationsstellen
Methods or arrangements for detection or correction of errors covered by this group involve such correction after the acquisition step with the aim of having a reliable input before the subsequent recognition. In contrast, group G06V 30/26 covers the methods and arrangements used after recognition with the aim of correcting the final output, by using additional information such as context.
