Abstract:

Geometric model fitting has been widely used in many computer vision tasks. However, it remains as a challenging task when handing multiple-structural data contaminated by noises and outliers. Most previous work on model fitting cannot guarantee the consistency of their solutions due to their randomness, precluding them from many real-world applications. In this research, we propose a fast two-view approximately deterministic model fitting scheme (called LGF), to provide consistent solutions for multiple-structural data. The proposed LGF scheme starts from defining preference function by preserving local neighborhood relationship, and then adopts the min-hash technique to roughly sample subsets. By this way, it is able to cover all model instances in data in the parameter space with a high probability. After that, LGF refines the previous sampled subsets by global-residual optimization. Furthermore, we propose a simple yet effective model selection framework to estimate the number and the parameters of model instances in data. Extensive experiments on real images show that the proposed LGF scheme is able to observe superior or very competitive performance on both accuracy and speed over several state-of-the-art model fitting methods.
