26 - * \br_property QString keys The meta-data key(s) used for Majority Voting.  
27 - * \br_property int numClasses The number of possible classes.  
28 - * \br_property QString outputKey The output metadata key which stores the a list with the index of the winning class set to 1.  
29 - * \br_property float thresh Allows users to specify a threshold for the first class, if exceeded the first class wins else class 2 wins.
