中文简介:
最近的工作表明人耳在不同受试者之间变化很大并且可以用于识别。因此,原则上,在识别系统内使用耳朵以及面部可以提高准确性和鲁棒性,特别是对于非正面视图。本文描述了使用基于头部和耳朵的3D可变形模型的构造的方法来研究该假设的工作。创建包含耳朵的模型的一个问题是现有的训练数据集包含噪声和部分遮挡。不是手动排除这些区域,而是开发了一种自动化该过程的分类器。当与稳健的配准算法结合时,所得到的系统使得能够使用较少约束的数据集有效地构建完整的可变形模型。该算法已经使用注册一致性,模型覆盖率和极简主义度量进行了评估,它们共同证明了该方法的准确性。为了更容易构建这项工作,源代码已在线提供。
课程简介: Recent work suggests that the human ear varies significantly between different subjects and can be used for identification. In principle, therefore, using ears in addition to the face within a recognition system could improve accuracy and robustness, particularly for non-frontal views. The paper describes work that investigates this hypothesis using an approach based on the construction of a 3D morphable model of the head and ear. One issue with creating a model that includes the ear is that existing training datasets contain noise and partial occlusion. Rather than exclude these regions manually, a classifier has been developed which automates this process. When combined with a robust registration algorithm the resulting system enables full head morphable models to be constructed efficiently using less constrained datasets. The algorithm has been evaluated using registration consistency, model coverage and minimalism metrics, which together demonstrate the accuracy of the approach. To make it easier to build on this work, the source code has been made available online.
