摘要

大多数从运动中提取结构的工作都假定跟踪与结构和运动的恢复是一个独立的问题。本文认为，在某些情况下，在估计结构和运动的过程中，使用原始图像来细化跟踪是有帮助的。我们通过提出两种算法来说明这一点:一种用于基于完全旋转的外观结构，另一种用于从三张图像中进行三维人脸建模。我们得出以下结论:只有在已知形状或形状变形类型的情况下才使用外观预测。否则，只使用目前已知的轨道可能会更好。

Is appearance-based structure from motion viable?

Most structure from motion work assumes that tracking is a separate issue from recovery of structure and motion. This paper argues that in certain cases, it helps to use the original images to refine the tracking in the course of estimating structure and motion. We illustrate this by presenting two algorithms: one for appearance-based structure from complete rotation and another for 3-D face modeling from three images. We come to the following conclusion: use appearance prediction only if the gross shape or type of shape deformation is known. Otherwise, one is very likely better off just using the currently known tracks.
