    The RTR SDK processes recognize the text of several frames in parallel on the available CPUs. Then the recognition results are merged in order to eliminate random recognition errors and get higher accuracy. RTR SDK does not returns the information about recognition confidence or suspiciousness for separate recognized characters, but you can obtain the result stability status for all extracted text. The result stability status is an estimate of how stable the result is, and whether it is likely to be improved by adding new frames. Please find more information about the RTRResultStabilityStatus enumeration and its constants in the Help file (RtrSdkDevelopersGuide.pdf).
