统计形状建模是一种广泛使用的技术，用于表示和分析人口中存在的形状和形状变化。统计形状模型对高维形状空间中的分布进行建模，其中每个形状由单个点表示。我们提出了一个设计研究的直观探索和可视化的形状空间和形状模型。我们的方法侧重于这些空间的双空间性质。高维形状空间表示总体，而对象空间表示与形状空间中的点相关联的3D对象的形状。3D对象视图提供单个形状的局部细节。形状空间中的高维点使用2D散点图投影进行可视化，其轴可以交互式操纵。这导致动态散点图，进一步扩展，每个点被可视化为它所代表的对象形状的小版本。我们进一步加强人口对象的二重性与一种新的类型的视图，旨在形状比较。这种新的“形状演化视图“将形状可变性沿形状空间中的单个轨迹沿着可视化，并且用作上述两个空间之间的链接。我们的三视图探索概念强烈强调所有空间之间的相互联系。将光标移动到散点图或演变视图上，形状将动态插值并显示在对象视图中。相反，对象视图中的相机操作会影响其他视图中的对象可视化。我们提出了一个GPU加速的实现，并使用一些现实世界的情况下，三视图的方法的有效性。在这些中，我们演示了如何使用这种多视图方法来直观地探索统计形状模型的重要方面，包括特异性，紧凑性和重建误差。
Statistical shape modeling is a widely used technique for the representation and analysis of the shapes and shape variations present in a population. A statistical shape model models the distribution in a high dimensional shape space, where each shape is represented by a single point. We present a design study on the intuitive exploration and visualization of shape spaces and shape models. Our approach focuses on the dual-space nature of these spaces. The high-dimensional shape space represents the population, whereas object space represents the shape of the 3D object associated with a point in shape space. A 3D object view provides local details for a single shape. The high dimensional points in shape space are visualized using a 2D scatter plot projection, the axes of which can be manipulated interactively. This results in a dynamic scatter plot, with the further extension that each point is visualized as a small version of the object shape that it represents. We further enhance the population-object duality with a new type of view aimed at shape comparison. This new " shape evolution view " visualizes shape variability along a single trajectory in shape space, and serves as a link between the two spaces described above. Our three-view exploration concept strongly emphasizes linked interaction between all spaces. Moving the cursor over the scatter plot or evolution views, shapes are dynamically interpolated and shown in the object view. Conversely , camera manipulation in the object view affects the object visualizations in the other views. We present a GPU-accelerated implementation, and show the effectiveness of the three-view approach using a number of real-world cases. In these, we demonstrate how this multi-view approach can be used to visually explore important aspects of a statistical shape model, including specificity, compactness and reconstruction error.
