How to rerun Tesseract OCR?

Tesseract OCR is running on iOS 8.x, on an iPhone 5. It typically does well on the first image (from camera), but subsequently produces garbage (as the "recognized text").

I presume there is some kind of internal state in the Tesseract library that needs to be cleared before each re-run (i.e., same app instance, but for all OCR runs after the first). Does anybody know off-hand what, if any, special steps should be taken before a re-run of Tesseract?

Thanks.

Call api.Clear() or api.ClearAdaptiveClassifier().
