Guaranteed Outlier Removal for Rotation Search

no code implementations • ICCV 2015 • Alvaro Parra Bustos, Tat-Jun Chin

Used as a preprocessor to prune a large portion of the outliers from the input data, our method enables substantial speed-up of rotation search algorithms without compromising global optimality.

Fast Rotation Search with Stereographic Projections for 3D Registration

no code implementations • CVPR 2014 • Alvaro Parra Bustos, Tat-Jun Chin, David Suter

In this work, assuming that the translation parameters are known, we focus on constructing a fast rotation search algorithm.
