Deeply Exploiting Long-Term View Dependency for 3D Shape Recognition

Yong Xu, Chaoda Zheng, Ruotao Xu, Yuhui Quan
2019 IEEE Access  
Incorporating the aggregation module into a standard convolutional network architecture, we develop an effective method for 3D shape classification and retrieval.  ...  Most existing view-based methods treat the views of an object as an unordered set, which ignores the dynamic relations among the views, e.g. sequential semantic dependencies.  ...  In many scenarios, the views are generated by a sequential process, e.g. moving a camera around the object. Therefore, the views may contain many sequential or temporal semantic dependencies.  ...
