项目摘要

We have achieved the following results regarding the Shape similarity retrieval of 3D models and digital watermarking of 3D models.Shape based retrieval :・Shape similarity comparison methods(1)Envelopes of rotational moments, etc. of aligned 3D models. (A referred Int'l Conf. paper PG2002 and a journal paper.)(2)2D histogram of distance and angle of a point-set version of the model. (A refereed int'l conf. paper TPCG 2003 and an international journal paper.)(3)Multiple view image comparison approach to shape comparison. (A refereed int'l conf. paper ACM MIR 2003.)・Multiresolution approach to shape similarity comparison. (A refereed international conference paper PG2003.)・3D model retrieval interface using relevance feedback based on a statistical learning method. (A refereed domestic conference and a journal paper.)・A 3D model retrieval interface based on automatic classification (submitted).・Combination of multiresolution, heterogeneous shape comparison methods for improved 3D model retrieval (submitted.)・Reduction of feature vector dimension for efficient shape model retrieval (submitted.)Digital watermarking :・A frequency domain approach to watermarking 3D mesh models. (Refereed domestic conferences, a refereed int'l conference, and an international journal paper.)・A frequency domain watermarking method for point set 3D models. (A refereed int'l conference CW2004.)

在三维模型形状相似性检索和三维模型数字水印方面取得了以下研究成果：·形状相似性比较方法(1)对齐三维模型的旋转矩包络等。(引用的国际会议。一篇论文PG2002和一篇期刊论文。)(2)距离和角度的二维直方图模型的点集版本。(被裁判的国际会议。论文TPCG 2003和一篇国际期刊论文。)(3)形状比较的多视角图像比较法。(被裁判的国际会议。ACM Mir 2003年的论文。)·形状相似性比较的多分辨率方法。(经评审的国际会议论文PG2003。)·使用基于统计学习方法的相关反馈的3D模型检索界面。(一次经过评审的国内会议和一篇期刊论文。)·基于自动分类的3D模型检索界面(已提交)。·结合多分辨率、不同形状比较方法改进三维模型检索(已提交)。·降低特征向量维度以实现有效的形状模型检索(已提交)。数字水印：·一种为3D网格模型添加水印的频域方法。(国内会议、国际会议和国际期刊论文。)·提出了一种点集三维模型的频域水印方法。(国际裁判会议CW2004。)
