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.

Visual perception of shape-transforming processes: ‘Shape Scission’
Cognition, 2019Shape-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.

Shape Transformation Mechanism of Gold Nanoplates
ACS Nano, 2023Shape 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 diffusion of surface atoms, all of which are important in overall shape transformation. However, it

Transformation Direction Influences Shape-Similarity Judgments
Psychological Science, 2009Three 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, 2021Nanomaterials 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 ...

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, 1996The 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, 2011Normally, 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.

Shape Transformers for Material and Shape Selection
Volume 5a: 17th International Conference on Design Theory and Methodology, 2005This paper presents a method for selecting materials, cross-section shapes, and combinations thereof. The novelty of the method is the definition of Shape Transformers. These parameters are dimensionless measures of the geometric quantities of a cross-section.
