On the Instability of Relative Pose Estimation and RANSAC's Role

no code implementations29 Dec 2021 Hongyi Fan, Joe Kileel, Benjamin Kimia

In this paper we study the numerical instabilities of the 5- and 7-point problems for essential and fundamental matrix estimation in multiview geometry.

GPU-Based Homotopy Continuation for Minimal Problems in Computer Vision

no code implementations7 Dec 2021 Chiang-Heng Chien, Hongyi Fan, Ahmad Abdelfattah, Elias Tsigaridas, Stanimire Tomov, Benjamin Kimia

Homotopy Continuation (HC) can solve more complex problems without the stability issues, and with guarantees of a global solution, but they are known to be slow.

Trifocal Relative Pose from Lines at Points and its Efficient Solution

1 code implementation23 Mar 2019 Ricardo Fabbri, Timothy Duff, Hongyi Fan, Margaret Regan, David da Costa de Pinho, Elias Tsigaridas, Charles Wampler, Jonathan Hauenstein, Benjamin Kimia, Anton Leykin, Tomas Pajdla

We present a new minimal problem for relative pose estimation mixing point features with lines incident at points observed in three views and its efficient homotopy continuation solver.
