Optimization is a powerful paradigm for expressing and solving problems in a wide range of areas, and has been successfully applied to many vision problems. Discrete optimization techniques are especially interesting since, by carefully exploiting problem structure, they often provide nontrivial guarantees concerning solution quality. In this paper, we review dynamic programming and graph algorithms, and discuss representative examples of how these discrete optimization techniques have been applied to some classical vision problems. We focus on the low-level vision problem of stereo, the mid-level problem of interactive object segmentation, and the high-level problem of model-based recognition.
优化是一种在广泛领域中表达和解决问题的强大范例,并且已经成功应用于许多视觉问题。离散优化技术特别有趣,因为它们通过仔细利用问题结构,通常可以为解决方案质量提供非平凡的保证。在本文中,我们回顾了动态规划和图算法,并讨论了这些离散优化技术如何应用于一些经典视觉问题的代表性示例。我们专注于立体视觉的低级问题、交互式对象分割的中级问题和基于模型的识别的高级问题。
