Guaranteed Outlier Removal for Point Cloud Registration with Correspondences [PDF]

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2018
An established approach for 3D point cloud registration is to estimate the registration function from 3D keypoint correspondences. Typically, a robust technique is required to conduct the estimation, since there are false correspondences or outliers.

Polyferrocene‐Based Cubosomes: Conversion to Magnetic Mesoporous Microparticles, Supramolecular Modification, and Oxidation Response

Advanced Functional Materials, EarlyView.
Polyferrocene block copolymers are synthesized and assembled into micron‐sized polymer cubosomes with double diamond lattice and pore diameter of ≈30 nm. The ferrocene functionality is retained within the polymer cubosome wall as demonstrated on supramolecular modification, and oxidative disassembly.

A Programmable Semiconductor Containing Active Molecular Photoswitches Located in the Crystal's Volume Phase

Advanced Functional Materials, EarlyView.
A novel approach for the design of functional semiconductors is presented, which utilizes the excellent optoelectronic properties of layered hybrid perovskites and the possibility to introduce a molecular photoswitch as the organic spacer. This concept is successfully demonstrated on a coumarin‐based system with the possibility to change the bandgap ...

Velocity Dispersion of Dissolving OB Associations Affected by External Pressure of Formation Environment

, 2004
This paper presents a possible way to understand dissolution of OB associations (or groups). Assuming rapid escape of parental cloud gas from associations, we show that the shadow of the formation environment for associations can be partially imprinted ...

Multipurpose Transparent Nanocomposites for Gamma Spectroscopy, Pulse Shape Discrimination, Thermal Neutron Detection, Radiation Shielding, and High Refractive Index Applications

Advanced Functional Materials, EarlyView.
Materials exist that are useful for gamma scintillation, radiation shielding, neutron‐gamma pulse shape discrimination (PSD), thermal neutron detection, or high refractive index applications. While certain materials have exhibited optimal performance for each of these applications, none achieve multiple functions.

Robust SAR-assisted cloud removal via supervised align-guided fusion and bidirectional hybrid reconstruction

International Journal of Digital Earth
Cloud removal improves the quality of cloud-covered optical remote sensing images. The use of Synthetic Aperture Radar (SAR) images, which are known for their strong penetration capability and ability to reflect the geometrical features of ground objects,

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)

Advanced Functional Materials, EarlyView.
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

3D Registration of Aerial and Ground Robots for Disaster Response: An Evaluation of Features, Descriptors, and Transformation Estimation

, 2017
Global registration of heterogeneous ground and aerial mapping data is a challenging task. This is especially difficult in disaster response scenarios when we have no prior information on the environment and cannot assume the regular order of man-made ...
