Astonishing diversity: Semiconductor nanoparticles form numerous structures
lead sulfide nanoparticles hexagonal structure BCC
2021/8/5
The structure adopted by lead sulphide nanoparticles changes surprisingly often as they assemble to form ordered superlattices. This is revealed by an experimental study that has been conducted at DES...
A WEIGHTED CLOSED-FORM SOLUTION FOR RGB-D DATA REGISTRATION
RGB-D data dual-number quaternions registration loop closing globally consistent maps
2016/7/27
Existing 3D indoor mapping of RGB-D data are prominently point-based and feature-based methods. In most cases iterative closest point (ICP) and its variants are generally used for pairwise registratio...
