摘要：

为提高基于视图的三维模型分类算法准确度,结合多局部显著视图与卷积神经网络(CNN)提出一种新的三维模型分类算法。提取三维模型多视角下的局部视图,引入显著性评价,建立多局部显著视图集合,以合理表征原始三维模型,兼顾数据表示的完整性和多样性。在此基础上,综合单视图CNN,利用bagging策略构建面向三维模型分类任务的集成深度学习模型,从而提高分类器的泛化性和准确率。在ModelNet10数据集上的实验结果表明,该算法可有效提高分类准确率。

Abstract:

To improve the accuracy of view based 3D model classification algorithms,a 3D model classification algorithm based on multiple local salient views and Convolutional Neural Network(CNN) is proposed in this paper.Firstly,the local views of a 3D model are extracted from multi perspectives.Then,by evaluating the saliency of each extracted view,multiple local salient views are established to form a reasonable representation of the 3D model,which have the fine properties of integrity and diversity.Finally,integrating the single view based CNN,a 3D model classification oriented ensemble deep learning model is proposed by using the bagging strategy,so as to improve the generalization and accuracy of the classifier.Experimental results on ModelNet10 dataset show that this algorithm can effectively improve classification accuracy.

Key words: local view, Convolutional Neural Network(CNN), ensemble deep learning, salient view, 3D model classification
