The digit booster engine boosts “digit to digit” for alphanumeric fields and “alpha to digit” for numeric fields. The digit to digit booster provides optimized digit recognition. The alpha to digit booster also repairs digits that were recognized as letters.
Boosted objects are worktexts for fields, candidates and table cells. The workdoc itself remains unchanged. The engine supports multi-page documents, but the performance may decrease for multi-page documents with many fields and candidates. Resolutions higher than 300 DPI or lower than 96 DPI lead to boost failures.
The Format Analysis Engine delivers candidates for the Brainware Extraction Engine, so that re-learning is not required after activating the digit booster engine. For digit to digit boosting re-learning is definitely not useful. For alpha to digit boosting relearning might improve the results.
