摘 要:3D model retrieval is an important part of multimedia information *** solve the drawbacks of the traditional text-based method,current researches concentrate on the content-based 3D model ***, the performance of the content-based method isn’t satisfying because of the semantic *** this paper,we provide a method of semantic kernel PCA for dimensionality reduction and feature extraction in content-based 3D model *** data of users’long-term relevance feedback were used to construct a semantic kernel,and then we use the semantic kernel to assist Gaussian kernel in kernel PCA to reduce dimension of 3D model features. Experimental results on Princeton Shape Benchmark have shown the effectiveness of our proposed method.
