- duplicateFilter
@property (nonatomic, assign) NSTimeInterval duplicateFilter
Added in version 6.1.0
Determines the time interval in which captured texts with the same value are filtered out as duplicates. By default, when the same text is captured in consecutive frames, it is reported again as a new recognition. Use this property to change the interval or completely turn off duplicate filtering:
Setting this property to value smaller than zero, means that the same text will not be reported again until the capturing session has been stopped.
Setting this property to a value of zero means that the same text will be reported every time it is found.
Setting this property to a value larger than zero indicates the time that must pass between the same text to be reported again.
