Remarks
This specifies the possible IproPlus trade-off settings to be applied during
the recognition. This setting has a trade-off influence between
the accuracy and the speed of recognition. The precise influence depends
on the recognition module used. This setting may also influence which
auto-zoning and preprocess algorithm will be applied.
Any of these three settings can always be specified, however for some
recognition modules these are mapped internally into two values.
When the Page parser algorithm settings of the IproPlus is set
to DCM_AUTO and both parsers are available in the IproPlus configuration,
the IproPlus trade-off setting will determine which page parser algorithm will be applied.
Recognition module specific notes:
- RM_OMNIFONT_MOR : Depending on this setting, either a one-pass, a two-pass or a
two-pass with ACA (Adaptive Cell Analysis) recognition algorithm is used.
Recognition accuracy may also be affected by the use (and settings) of the checking
module. The combinations of these two settings result in five different
speed/accuracy user choices.
-
Two-pass with Adaptive Cell Analysis with spelling. TO_ACCURATE with checking module enabled.
-
Two-pass with spelling. TO_BALANCED with checking module enabled.
-
Two-pass. TO_BALANCED with checking disabled.
-
Single-pass with spelling. TO_FAST with checking module enabled.
-
Single-pass. TO_FAST with checking disabled.
- RM_OMNIFONT_MTX : This recognition module has a two-value trade-off setting:
internally the TO_ACCURATE and TO_BALANCED are mapped to the same setting.
- RM_HNR : This recognition module has a two-value trade-off setting: internally
the TO_ACCURATE and TO_BALANCED are mapped to the same setting. The TO_ACCURATE
means fewer misrecognized characters, but maybe more rejected ones.
- RM_RER : This recognition module has a two-value trade-off setting: internally the
TO_FAST and TO_BALANCED are mapped to the same setting.
-
All remaining recognition modules: These do not interpret this RMTRADEOFF setting.
Preprocess specific notes (for color and grey-scale images):
-
If resolution enhancement is set to RE_AUTO the enhancement depends on the current
trade-off setting according to the following: if trade-off is TO_FAST the resolution enhancement
RE_LEGACY, otherwise it is RE_STANDARD.
-
If trade-off is TO_FAST preprocess uses a faster, but less accurate deskew, binarization,
and despeckle algorithm than otherwise.
No trade-off setting is applied when Asian languages are being recognized.
