Execute the learning of Dictionary.
Leaning is executed using the characters registered in each label and the feature quantity of the sub patterns to
be generated based on those character images.
At this time, the number of sub patterns changes by changing "Leaning Type". The type and number of the
used feature quantity changes by changing "Recognition Speed".
Always execute "Learning" when Dictionary has been edited (Registered, added or deleted character patterns)
or when the setting of Learning type or Recognition speed has been changed.
1.
Select one from "Normal", "Rough (High-speed)" and "Fine (Low-speed)" in "Learning Type".
In Learning type, select the number of sub patterns to be automatically generated based on the registered
character patterns. The more sub patterns are available, the more stable Character recognition can be
performed. However, the execution time of leaning becomes longer.
Learning Type
Rough (High-speed)
Normal
Fine (Low-speed)
2.
Select either "Normal", "Normal" or "High Speed" in "Recognition Speed" .
The type and number of the feature quantity to be detected during learning changes according to the
recognition speed. To decrease the recognition speed, select "High Speed".
The change in the recognition speed affects recognition results. Check whether or not the recognition
result is the one you require by executing a test.
