Researches on 3D Model Retrieval Using Weighted Features
Xuemin Cheng · Journal of Changzhou Vocational College of Information Technology · 2011
Based on the original 3D model retrieval method,the paper proposes a method for 3D model retrieval adding weighted feature,and this method is applied to 3D model retrieval based on spherical harmonic.The effect of the retrieval exerted by the uneven sampling is proposed and balanced through increasing the proportion of sampling weights of the external sphere gradually which taking the ball of sampling area as ratio.The retrieval experiments are carried out on PSB and compared using a variety of evaluation.General results show that the proposed method is more effective than the original one.
