Mapping structural heterogeneity in three-dimensional biophotonic gyroid networks using position-resolved small-angle X-ray scattering

Abstract The wings of select Papilionid and Lycaenid butterflies contain a three-dimensional gyroid network of a solid cuticle phase in air. In butterfly scales, gyroid networks are optically interesting, as they create the green colour observed in the wings of these butterflies....

GeoHash3D: Robust and Efficient 6-DoF Pose Estimation from 3D Marker Sets

Accurately measuring the six degrees of freedom (6-DoF) pose of a sample is a critical prerequisite for applications in robotic sample handling, optical metrology, and industrial quality control. Our pose estimation problem requires matching a small, partial observation of 4–20 d...
