论文摘要
大多数工程合金的微结构都包含一些夹杂物和沉淀物,这可能会影响其性质,因此表征它们至关重要。在这项工作中,我们着重于开发名为弹头的异常检测的最先进的人工智能模型,以自动量化合金中杂质异常的程度。为此,我们引入了几种异常检测措施:空间,形状和区域异常,鉴于杂质已经标记了基于其目标,可以成功地检测到最异常的对象。前两个衡量的方法通过与邻域以及其自身形状的异常相比,每个对象的距离距离且较大,量化了每个对象的异常程度。最后一个措施结合了前两个,并突出显示了所有输入图像中最异常的区域,以进行以后的(物理)检查。基于少数代表性案例,呈现和分析模型的性能。我们强调的是,尽管此处介绍的模型是用于用于金相分析的,但大多数可以推广到更广泛的问题,其中需要对几何对象的异常检测。所有模型以及为这项工作创建的数据集,均可在以下网址公开获取:https://github.com/matanr/mlography。
The micro-structure of most of the engineering alloys contains some inclusions and precipitates, which may affect their properties, therefore it is crucial to characterize them. In this work we focus on the development of a state-of-the-art artificial intelligence model for Anomaly Detection named MLography to automatically quantify the degree of anomaly of impurities in alloys. For this purpose, we introduce several anomaly detection measures: Spatial, Shape and Area anomaly, that successfully detect the most anomalous objects based on their objective, given that the impurities were already labeled. The first two measures quantify the degree of anomaly of each object by how each object is distant and big compared to its neighborhood, and by the abnormally of its own shape respectively. The last measure, combines the former two and highlights the most anomalous regions among all input images, for later (physical) examination. The performance of the model is presented and analyzed based on few representative cases. We stress that although the models presented here were developed for metallography analysis, most of them can be generalized to a wider set of problems in which anomaly detection of geometrical objects is desired. All models as well as the data-set that was created for this work, are publicly available at: https://github.com/matanr/MLography.
