Name | Type | Description |
---|---|---|
higRecApproxRegex | const HIG_REC_APPROX_REGEX | The handle to an approximate regex instance. |
higRecDocument | const HIG_REC_DOCUMENT | A recognition document. |
match_result_array | const AT_REC_MATCH_RESULT** const | A pointer to a vector of match result instances. The approximate regex owns this data. Callers that require access to this data after the approximate regex is deleted must duplicate this data and assume ownership of the copy. |
match_result_size | AT_INT* const | The number of match results in match_result_array. |
This function does not process image pixels.
