A data-driven classification of 3D foot types by archetypal shapes based on landmarks
Costin Daniel Untaroiu (Virginia Tech, USA) (2020-01-30)The taxonomy of foot shapes or other parts of the body is important, especially for design purposes. We propose a methodology based on archetypoid analysis (ADA) that overcomes the weaknesses of previous methodologies used ... -
A Gaussian kernel for Kendall’s space of m-D shapes
Elsevier ScienceDirect (2023-08-15)In this paper, we develop an approach to exploit kernel methods with data lying on the m-D Kendall shape space. When data arise in a finite-dimensional curved Riemannian manifold, as in this case, the usual Euclidean ...

A new extrinsic sample mean in the shape space with applications to the boundaries of anatomical structures
Wiley (2016-02-16)Shape analysis is of great importance in many fields of medical imaging and computational biology. In this paper, we consider the shape space as the set of smooth planar immersed curves in inline image (parameterized curves) ... -
A review of spatiotemporal models for count data in R packages. A case study of COVID-19 data
MDPI (2021-07-01)Spatiotemporal models for count data are required in a wide range of scientific fields, and they have become particularly crucial today because of their ability to analyze COVID-19- related data. The main objective of this ...

Apparel sizing using trimmed PAM and OWA operators
Elsevier (2012-09)This paper is concerned with apparel sizing system design. One of the most important issues in the apparel development process is to define a sizing system that provides a good fit to the majority of the population. A ...

Archetypal analysis with missing data: see all samples by looking at a few based on extreme profiles
American Statistical Association (2019-05-13)In this paper we propose several methodologies for handling missing or incomplete data in Archetype analysis (AA) and Archetypoid analysis (ADA). AA seeks to find archetypes, which are convex combinations of data points, ...

Archetypal contour shapes
Università di Cassino e del Lazio Meridionale. Centro Editoriale di Ateneo (2019)Shapes are represented by contour functions from planar object outlines. Functional archetypal analysis is proposed to describe closed contour shapes. Each contour function is approximated by a convex combination of ...

Archetypal shapes based on landmarks and extension to handle missing data
Springer Verlag (2017-10)Archetype and archetypoid analysis are extended to shapes. The objective is to find representative shapes. Archetypal shapes are pure (extreme) shapes. We focus on the case where the shape of an object is represented by a ...

Attitude towards the incorporation of the selective collection of biowaste in a municipal solid waste management system. A case study
Elsevier (2014-12)European waste legislation has been encouraging for years the incorporation of selective collection systems for the biowaste fraction. European countries are therefore incorporating it into their current municipal solid ...

Consumer behaviour and environmental education in the field of waste electrical and electronic toys: A Spanish case study
Elsevier (2015-02)This paper reports on a project focused on obtaining the current consumption and disposal habits of electrical and electronic toys from a survey aimed at parents of children of nine pre- and primary schools. In addition, ...

Erythrocyte shape classification using integral-geometry-based methods
Springer (2015)Erythrocyte shape deformations are related to different important illnesses. In this paper, we focus on one of the most important: the Sickle cell disease. This disease causes the hardening or polymerization of the hemoglobin ...

Generalized Linear Models for Geometrical Current predictors. An application to predict garment fit
SAGE Publications (2019)The aim of this paper is to model an ordinal response variable in terms of vector-valued functional data included on a vector-valued RKHS. In particular, we focus on the vector-valued RKHS obtained when a geometrical ...

Generalized partially linear models on Riemannian manifolds
Royal Statistical Society (2020-05-03)We introduce generalized partially linear models with covariates on Riemannian manifolds. These models, like ordinary generalized linear models, are a generalization of partially linear models on Riemannian manifolds that ...

Geometric analysis of planar shapes with applications to cell deformations
International Society for Stereology (2015-07)Shape analysis is of great importance in many fields such as computer vision, medical imaging, and computational biology. In this paper we focus on a shape space in which shapes are represented by means of planar closed ...

Inhomogeneous K-function for germ–grain models
Elsevier (2016)In this paper, we propose the definition of the inhomogeneous K-function for germ–grain models, based on the reduced second order measure for general random sets. In general, grains in a germ–grain model can overlap, ...

Intrinsic sample mean in the space of planar shapes
Elsevier (2016-12)In this paper we consider the shape space as the set of smooth simple closed curves in R2R2 (parameterized curves), modulo translations, rotations and scale changes. An algorithm to obtain the intrinsic average of a sample ...

Life cycle assessment of ceramic tiles: Environmental and statistical analysis
Springer (2011)Purpose. The aim of this paper is to conduct a life cycle assessment study of ceramic tiles (single-fired glazed stoneware) in order to identify the stages that produce the greatest impact on the environment and the materials ...

Modeling of female human body shapes for apparel design based on cross mean sets
Elsevier (2014)This paper is concerned with a method to build prototypes of human bodies that can be used for apparel design. One of the most important issues in the apparel development process is to define a sizing system to provide a ...

Modelling municipal waste separation rates using generalized linear models and beta regression
Elsevier (2011)Most cities are actually very concerned about the economic viability of waste management and also about the impact they may have on the environment. Economical, social and cultural factors in the population will determine ...
