Shape Transformers: Topology‐Independent 3D Shape Models Using Transformers

Computer Graphics Forum, 2022
AbstractParametric 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, 2003
Summary: 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.

Shape features in distance transforms

SPIE Proceedings, 1993
Shape 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.

Visual perception of shape-transforming processes: ‘Shape Scission’

Cognition, 2019
Shape-deforming processes (e.g., squashing, bending, twisting) can radically alter objects' shapes. After such a transformation, some features are due to the object's original form, while others are due to the transformation, yet it is challenging to separate the two.

Transformation Direction Influences Shape-Similarity Judgments

Psychological Science, 2009
Three experiments provide evidence that the perceived similarity between two images is systematically affected by the inherent direction of a transformation that links the two. Participants were shown short animations morphing one object into another from the same basic category.

Shape and nanocrystal transformations

Science, 2021
Nanomaterials Cation exchange reactions that change the composition of a nanocrystal (NC) under mild conditions usually preserve the sublattice of the larger anions. Li et al. found that the shape of roxbyite (Cu1.8S) nanocrystals, which have a distorted, hexagonal, close-packed sulfide anion sublattice, affected the outcome of exchange reactions with ...

Transformation of shape

Proceedings of the Royal Society of London. Series B - Biological Sciences, 1950
We are lucky to be able to discuss to-day so simple a concept as that of ‘growth’. Growth means change of size, and the size of an organism is something definite, unambiguous and measurable. It has been more than once suggested that ‘growth’ is an all but impenetrably obscure concept because it relates to a very heterogeneous process, i. e.

Surface-Aggregate Shape Transformation

Langmuir, 1996
The structure of surfactant surface-aggregates can be controlled by mixing two surfactants which, individually, form different surface-aggregate structures. Using atomic force microscopy (AFM), we have found that mixtures of (dodecyldimethylammonio)propanesulfonate (DDAPS) and dodecyltrimethylammonium bromide (DTAB) at the interface between mica and ...

Gait recognition using shape trace transform

2011 IEEE International Symposium on IT in Medicine and Education, 2011
Normally, the gait of each person has individual style so it can be used for human identification. In this paper, the gait recognition using shape trace transform is presented for human identification. First step, gait recognition using shape trace transform used the silhouettes input.
