| 摘 要： | 基于形状分布算法提出了一种加强细节检索的算法。该算法首先将经过预处理的模型分割为N个子模块并分别进行特征提取，然后构造每个子模块的形状分布直方图，最后通过比较子模块的相似度来计算模型的相似度。该算法相比形状分布算法比较准确地计算出了模型间的相似性，有效地提高了细节的分辨，解决了外形相近但细节不同的问题。

| Abstract: | This paper proposed a new shape distribution method based on enhancing 3D model detail. First, segmented the preprocessed model into a set of blocks. Second, processed these blocks to feature extraction separately and constructed the feature histograms for each block.Finally, according to calculating the similarity between blocks, achieved the similarity of 3D models. This method was more accurately to compute the similarity between models than shape distribution. And increased the distinguishment of details. It resolved the problem of the similar shape but dissimilar detail. |
