Attributes are semantic visual properties shared by objects. They have been shown to improve object recognition and to enhance content-based image search. While attributes are expected to cover multiple categories, e.g. a dalmatian and a whale can both have "smooth skin", we find that the appearance of a single attribute varies quite a bit across categories. Thus, an attribute model learned...

The paper borrowed researching achievements in text retrieval field, describe the semantics of single model by using annotation, and present the semantics of 3D models by using semantic tree, based on the semantic similarity between the retrieval terms and semantic tree nodes with WordNet, and return the model that has strong semantic correlation. A flexible return policy is proposed to filter the...
