AI总结:

本文比较了基于高程图的SVM和决策树方法与基于参数等高线拟合的方法,在自动检测小提琴宽度减少方面,等高线方法表现更优。

摘要:

我们探索了使用3D摄影测量网格自动检测小提琴宽度减少的方法。我们比较了应用于基于几何的原始表示(由高程图构建)的SVM和决策树,与更针对性的方法,该方法依赖于参数等高线拟合的特征工程。尽管高程图偶尔能取得良好结果,但其性能无法超越基于等高线的输入。

英文摘要:

We explore the automatic detection of violin width reduction using 3D photogrammetric meshes. We compare SVM and Decision Trees applied to a geometry-based raw representation built from elevation maps with a more targeted, feature-engineered approach relying on parametric contour lines fitting. Although elevation maps occasionally achieve strong results, their performance does not surpass that of the contour-based inputs.
