we evaluated different combinations of feature sets
and different numbers of input views. These reports
can be helpful for further view-based retrieval system.
The comparison also demonstrated that the proposed
method can get more accurate results than two known
methods.
Currently, our retrieval method is designed for
articulated objects in which the limbs are rigid.
One possible extension is to incorporate deformation
methods, e.g. (Chen et al., 2013), for retrieving ob-
jects with surface deformation. Recently, the deep
learning techniques succeed in various vision prob-
lems. Our current method is relatively low-cost in
computation, and another possible future work is to
incorporate the features extracted from learning meth-
ods, e.g.(Su et al., 2015).
