Behavior of 
on datasets with increasing noise level: (top) Average difference between 
of XYW and all other 19 triplets across 19 triplets. The error bars correspond to standard deviation. (bottom) Ratio of average 
of XYW and average 
of other 19 triplets. The x-axis corresponds to the index i of the subset noise level, such that the number of flipped samples in a set is 25(i + 1). The maximum at 20 corresponds to 100% of the 500 being subjected to random flips.
