Geometric Viewpoint Learning with Hyper-Rays and Harmonics Encoding

no code implementations ICCV 2023 Zhixiang Min, Juan Carlos Dibene, Enrique Dunn

1) We propose a generalized viewpoint representation forgoing the analysis of photometric pixels in favor of encoded viewing ray embeddings attained from point cloud learning frameworks.

General Planar Motion from a Pair of 3D Correspondences

no code implementations ICCV 2023 Juan Carlos Dibene, Zhixiang Min, Enrique Dunn

Instead, we enforce geometric constraints identifying, in closed-form, a unique planar motion solution from an orbital set of geometrically consistent SE(3) motion estimates.

LASER: LAtent SpacE Rendering for 2D Visual Localization

1 code implementation CVPR 2022 Zhixiang Min, Naji Khosravan, Zachary Bessinger, Manjunath Narayana, Sing Bing Kang, Enrique Dunn, Ivaylo Boyadzhiev

LASER introduces the concept of latent space rendering, where 2D pose hypotheses on the floor map are directly rendered into a geometrically-structured latent space by aggregating viewing ray features.

VOLDOR: Visual Odometry from Log-logistic Dense Optical flow Residuals

1 code implementation CVPR 2020 Zhixiang Min, Yiding Yang, Enrique Dunn

We propose a dense indirect visual odometry method taking as input externally estimated optical flow fields instead of hand-crafted feature correspondences.
