Disjunctive normal shape models [PDF]
2015 IEEE 12th International Symposium on Biomedical Imaging (ISBI), 2015 A novel implicit parametric shape model is proposed for segmentation and analysis of medical images. Functions representing the shape of an object can be approximated as a union of N polytopes. Each polytope is obtained by the intersection of M half-spaces.

Vertex‐level three‐dimensional shape deformability measurement based on line segment advection
IET Computer Vision, 2018 Measuring the intrinsic deformability of arbitrary small‐scale subdivision of a shape is an interesting meanwhile valuable research topic. Such measurement can be directly utilised as a reliable criteria to partition shape into small components and then ...

Modelling and graphing the Wi-Fi wave field using the shape function
Open Physics, 2022 This article deals with modelling the Wi-Fi wave field, which is not visible to the naked eye, into a mathematical structure for assigning colours to observe the wave strength change compared to the source layout’s location correlation of obstacles in ...

Medical Image Analysis, 2013 We present a method to compute the conditional distribution of a statistical shape model given partial data. The result is a "posterior shape model", which is again a statistical shape model of the same form as the original model. This allows its direct use in the variety of algorithms that include prior knowledge about the variability of a class of ...

A Computational Model of Multidimensional Shape [PDF]
International Journal of Computer Vision, 2010 We develop a computational model of shape that extends existing Riemannian models of curves to multidimensional objects of general topological type. We construct shape spaces equipped with geodesic metrics that measure how costly it is to interpolate two shapes through elastic deformations.

Modelling of human torso shape variation inferred by geometric morphometrics.
PLoS ONE, 2022 Traditional body measurement techniques are commonly used to assess physical health; however, these approaches do not fully represent the complex shape of the human body.
