Shape Transformation Mechanism of Gold Nanoplates
ACS Nano, 2023 Shape control is of key importance in utilizing the structure–property relationship of nanocrystals. The high surface-to-volume ratio of nanocrystals induces dynamic surface reactions on exposed facets of nanocrystals, such as adsorption, desorption, and

Shape Transformers: Topology‐Independent 3D Shape Models Using Transformers
Computer Graphics Forum, 2022AbstractParametric 3D shape models are heavily utilized in computer graphics and vision applications to provide priors on the observed variability of an object's geometry (e.g., for faces). Original models were linear and operated on the entire shape at once. They were later enhanced to provide localized control on different shape parts separately.

ENHANCED HIERARCHICAL SHAPE MATCHING FOR SHAPE TRANSFORMATION
International Journal of Shape Modeling, 2003Summary: The quality of 3D object transformation very often relies on the quality of the matching between the two objects. Geometric considerations regarding scale, rotation and translation, and user defined constraints are used to control the matching.

Medial Axis Transformation of a Planar Shape
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1982The medial axis transformation is a means first proposed by Blum to describe a shape. In this paper we present a 0(n log n) algorithm for computing the medial axis of a planar shape represented by an n-edge simple polygon. The algorithm is an improvement over most previously known results interms of both efficiency and exactness and has been ...

Shape features in distance transforms
SPIE Proceedings, 1993Shape features characterizing patterns represented by their distance transform are illustrated. The role they can play in pattern decomposition is described with reference to a process based on the detection of a number of pixels significant for shape interpretation.

Dynamic of the Earth shape transformation
Kinematika i fizika nebesnyh tel (Online), 2017Planetary dynamics of century-long Earth shape changes is studied based on the approximation of the physical Earth surface by a biaxial ellipsoid. Trends in century-long changes of Earthshape parameters were revealed from the analysis of the following data: modern GNSS measurements on permanent stations in the Northern and Southern hemispheres and ...
