22.2.3.2 Pattern Matching Mapping
The pixel patterns of the text area are compared with patterns in the data base and then
rough digitals are created
22.2.3.3 Error Correction on Plane of Projection
The rough digitals are compared with dictionaries (Intelligent Character Recognition,
ICR), and evaluated in regards to their probable correctness by linguistical and statistical
means. According to this evaluation, the text will be output or, if required, will be further
processed with modied parameters and another layout and pattern recognition.
22.2.3.4 Error Correction on Word Level
Handwritten letters that can’t be recognized separately will be recognized by comparing
global characteristics with dictionaries. The accurateness (Intelligent Word Recognition,
IWR) decreases with the growing size of the integrated dictionaries.
