Abstract: A novel content-based retrieval algorithm is proposed for meeting 3D object retrieval.Firstly,based on the analysis of shortcomings of existing view-based 3D model retrieval algorithm,so the concept of lightfield hybrid descriptor(denoted as HD) is presented and 3D object retrieval frame based on multi-feature relevance feedback learning is developed.Then overall framework HD,which is made of 3 sub-descriptors,is discussed and how to construct HD is described.Secondly,the 3D object retrieval algorithm based on multiple support vector machines fusion and the relevance feedback learning is used to improve accuracy and effective of 3D object retrieval.In the end,some experiments are done to analyze retrieval performances based on HD and relevance feedback learning.The results show that the proposed method is effective.
