Robust Non-parametric Data Fitting for Correspondence Modeling
Wen-Yan Lin, Ming‐Ming Cheng, Shuai Zheng, Jiangbo Lu, Nigel T. Crook · 2013
We propose a generic method for obtaining nonparametric image warps from noisy point correspondences. Our formulation integrates a huber function into a motion coherence framework. This makes our fitting function especially robust to piecewise correspondence noise (where an image section is consistently mismatched). By utilizing over parameterized curves, we can generate realistic nonparametric image warps from very noisy correspondence. We also demonstrate how our algorithm can be used to help stitch images taken from a panning camera by warping the images onto a virtual push-broom camera imaging plane.
