当光度测定信息不丰富或过于复杂而无法进行分析建模时，理解线条图如何传达三维性对于解释表面感知至关重要。我们在此提出了一种计算模型，用于将线条图解释为三维表面，该模型基于沿极值和不连续边界的局部表面方向的约束。描述了两个关键过程的具体技术：从图像中的二维投影恢复空间曲线（例如表面边界）的三维构象，以及从沿极值边界的方向约束插值平滑表面。讨论了该模型与低水平视觉一般理论的相关性。
Understanding how line drawings convey tri-dimensionality is of fundamental importance in explaining surface perception when photometry is either uninformative or too complex to model analytically.We put forward here a computational model for interpreting line drawings as three-dimensional surfaces, based on constraints on local surface orientation along extremal and discontinuity boundaries. Specific techniques are described for two key processes: recovering the three-dimensional conformation of a space curve (e.g., a surface boundary) from its two-dimensional projection in an image, and interpolating smooth surfaces from orientation constraints along extremal boundaries. The relevance of the model to a general theory of low-level vision is discussed.
