摘要:

将几何模型拟合到受离群值污染的数据上可证明是困难的。许多计算机视觉系统依赖于随机采样算法来解决鲁棒拟合,其不提供最优性保证和误差界。因此,至关重要的是开发新的方法,可以弥合昂贵的精确解决方案和无法提供质量保证的快速制造之间的差距。在本文中,我们提出了一个混合量子经典算法的鲁棒拟合。我们的核心贡献是一个新的强大的拟合配方,解决了一系列的整数规划和终止的全球解决方案或错误界。组合子问题服从量子退火,这有助于有效地收紧边界。虽然我们对量子计算的使用并没有克服鲁棒拟合的基本困难,但通过提供误差范围,我们的算法是对随机算法的实际改进。此外,我们的工作代表了量子计算在计算机视觉中的具体应用。我们目前使用实际的量子计算机(D-Wave Advantage)和通过模拟获得的结果。源代码:www. example. com

英文摘要:

Fitting geometric models onto outlier contaminated data is provably intractable. Many computer vision systems rely on random sampling heuristics to solve robust fitting, which do not provide optimality guarantees and error bounds. It is therefore critical to develop novel approaches that can bridge the gap between exact solutions that are costly, and fast heuristics that offer no quality assurances. In this paper, we propose a hybrid quantum-classical algorithm for robust fitting. Our core contribution is a novel robust fitting formulation that solves a sequence of integer programs and terminates with a global solution or an error bound. The combinatorial subproblems are amenable to a quantum annealer, which helps to tighten the bound efficiently. While our usage of quantum computing does not surmount the fundamental intractability of robust fitting, by providing error bounds our algorithm is a practical improvement over randomised heuristics. Moreover, our work represents a concrete application of quantum computing in computer vision. We present results obtained using an actual quantum computer (D-Wave Advantage) and via simulation.
