摘要:

持久同源性(PH)是拓扑数据分析领域的一个重要工具,它是将数据在不同分辨率下的同源性抽象表示为持久图(PD)。在这项工作中,我们建立一个以上的PD表示的一个单一的图像的基础上的地标选择方法,被称为本地二进制模式,编码不同类型的本地纹理的图像。我们采用了不同的PD矢量化,持久性景观,持久性图像,持久性分箱(贝蒂曲线)和统计。我们使用乳房X线摄影扫描在两个公开的乳房异常检测数据集上测试了基于PH的建议地标的有效性。在两个数据集中,基于标志的PH获得的检测异常乳腺扫描的灵敏度超过90%。最后,实验结果给出了使用不同类型的PD向量化的新见解,这有助于将PH与机器学习分类器结合使用。

英文摘要:

An Important tool in the field topological data analysis is known as persistent Homology (PH) which is used to encode abstract representation of the homology of data at different resolutions in the form of persistence diagram (PD). In this work we build more than one PD representation of a single image based on a landmark selection method, known as local binary patterns, that encode different types of local textures from images. We employed different PD vectorizations using persistence landscapes, persistence images, persistence binning (Betti Curve) and statistics. We tested the effectiveness of proposed landmark based PH on two publicly available breast abnormality detection datasets using mammogram scans. Sensitivity of landmark based PH obtained is over 90% in both datasets for the detection of abnormal breast scans. Finally, experimental results give new insights on using different types of PD vectorizations which help in utilising PH in conjunction with machine learning classifiers.
