Recommended Changes

Performance Changes

These do not require any code changes from your side, and are just underlying changes we made to SmartZone OCR to enhance its performance. In addition to the improved speed, SmartZone OCR 5 could have slightly different confidence values than SmartZone OCR 4 due to changes in the underlying SmartZone engine.

SmartZone OCR has separate worker processes for both 32 and 64 bit systems. This eliminates the thunking layer when processing in a 64 bit thread increasing performance. The two different worker processes are compiled to optimize performance on the user’s system and produce the exact same output.
