    • closedAccess   A new extrinsic sample mean in the shape space with applications to the boundaries of anatomical structures 

      Gual-Arnau, Ximo; Ibáñez Gual, Maria Victoria; Simó, Amelia 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) ...

    • closedAccess   Erythrocyte shape classification using integral-geometry-based methods 

      Gual-Arnau, Ximo; Herold-García, Silena; Simó, Amelia 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 ...

    • openAccess   Generalized Linear Models for Geometrical Current predictors. An application to predict garment fit 

      Barahona-Albiol, Sònia; Centella, P.; Gual-Arnau, Ximo; Ibáñez Gual, Maria Victoria; Simó, Amelia 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 ...

    • openAccess   Geometric analysis of planar shapes with applications to cell deformations 

      Gual-Arnau, Ximo; Herold-García, Silena; Simó, Amelia 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 ...

    • closedAccess   Shape description from generalized support functions 

      Gual-Arnau, Ximo; Simó, Amelia; Herold-García, Silena Elsevier (2013)
      The generalized support function is considered to be a representation of shape properties of compact connected sets in R2. Some interesting properties are studied and several parameters are defined for use in shape description ...

    • openAccess   Unsupervised classification of children’s bodies using currents 

      Barahona, S.; Gual-Arnau, Ximo; Ibáñez Gual, Maria Victoria; Simó, Amelia Springer Verlag (2018-06)
      Object classification according to their shape and size is of key importance in many scientific fields. This work focuses on the case where the size and shape of an object is characterized by a current. A current is a ...
