Shaping Phases by Phasing Shapes

ACS Nano, 2011
Incorporation of shape-shifting building blocks into self-assembled systems has emerged as a promising concept for dynamic structural control. The computational work by Nguyen et al. reported in this issue of ACS Nano examines the phase reconfigurations and kinetic pathways for systems built from shape-shifting building blocks.

Computing with Shapes

Journal of Visual Languages & Computing, 2001
Visual languages represent a response to the communicational challenges posed by end-user computing, but lack established computability frameworks for evaluating their computational power. In this paper, we introduce a computability model?called shape completion system?for the restricted, but important, case in which the visual representation of the ...

The hue of shapes.

Journal of Experimental Psychology: Human Perception and Performance, 2013
This article presents an experimental study on the naturally biased association between shape and color. For each basic geometric shape studied, participants were asked to indicate the color perceived as most closely related to it, choosing from the Natural Color System Hue Circle.

On the Orientability of Shapes

IEEE Transactions on Image Processing, 2006
The orientation of a shape is a useful quantity, and has been shown to affect performance of object recognition in the human visual system. Shape orientation has also been used in computer vision to provide a properly oriented frame of reference, which can aid recognition.

Shape Registration by Optimally Coding Shapes

IEEE Transactions on Information Technology in Biomedicine, 2008
This paper formulates shape registration as an optimal coding problem. It employs a set of landmarks to establish the correspondence between shapes, and assumes that the best correspondence can be achieved when the polygons formed by the landmarks optimally code all the shape contours, i.e., obtain their minimum description length (MDL).

Buildings and Organizations: The Shaping and the Shaped

HERD: Health Environments Research & Design Journal, 2008
The words of Winston Churchill, spoken in 1943, provide the philosophical basis for this study of the social implications of the built environment: “We shape our buildings and afterward our buildings shape us.” Using the work of ecological psychologists, sociologists, and organizational design theorists, this paper explores the reciprocal relationship

Shape Vocabulary: A Robust and Efficient Shape Representation for Shape Matching

IEEE Transactions on Image Processing, 2014
In this paper, a learning-based shape descriptor for shape matching is demonstrated. Formulated in a bag-of-words like framework, the proposed method summarizes the local features extracted from certain shape to generate a integrated representation. It contributes to the speed-up of shape matching, since the distance metric in the vector space analysis

IMMOBILIZING A SHAPE

International Journal of Computational Geometry & Applications, 1999
Let shape P be any simply-connected set in the plane, bounded by a Jordan curve, that is not a circular disk. We say that a set of points I on the boundary of P immobilize the shape if any rigid motion of P in the plane causes at least one point of I to penetrate the interior of P. We prove that four points always suffice to immobilize any shape. For a

Visualization of Shape Motions in Shape Space

IEEE Transactions on Visualization and Computer Graphics, 2013
Analysis of dynamic object deformations such as cardiac motion is of great importance, especially when there is a necessity to visualize and compare the deformation behavior across subjects. However, there is a lack of effective techniques for comparative visualization and assessment of a collection of motion data due to its 4-dimensional nature, i.e.,
