feature vectors of a kind of key pose with same mark. And then, we note the
two nearest objects in retrieval instance as 1 X and 2 X respectively. Finally,
we apply the construction algorithm of hyper sausage neuron with the
parameters X , 1 X , 2 X and a threshold r by Eq4.1-4.3. If the sign of
calculating result ( ) HSN f X is plus, the feature vector X can be considered
as a similar object to the kind of key pose, and be remarked by same mark of
the key pose.
