    • A new thresholding approach for automatic generation of polygonal approximations 

      Fernández García, Nicolás Luis; Moral Martínez, Luis del; Carmona Poyato, Ángel; Medina-Carnicer, R.; Madrid-Cuevas, F.J. (Elsevier, 2016)
      The present paper proposes a new algorithm for automatic generation of polygonal approximations of 2D closed contours based on a new thresholding method. The new proposal computes the signi cance level of the contour points ...

    • Assessing polygonal approximations: A new measurement and a comparative study 

      Fernández García, Nicolás Luis; Moral Martínez, Luis del; Carmona Poyato, Ángel; Madrid-Cuevas, F.J.; Medina-Carnicer, R. (Elsevier, 2023)
      Two proposals related to the evaluation of polygonal approximations are presented in this document. First, a new measurement, called normalized compression ratio and adjustment error (NCA), to provide a fair evaluation of ...

    • Contribución al reconocimiento de objetos 2D mediante aproximaciones poligonales 

      Moral Martínez, Luis del (Universidad de Córdoba, UCOPress, 2017)
      En la presente Tesis Doctoral se realizan aportaciones novedosas en las etapas de descripción e interpretación del proceso de reconocimiento de objetos bidimensionales. Se proponen nuevas técnicas de umbralización unimodal ...

    • Unsupervised generation of polygonal approximations based on the convex hull 

      Fernández García, Nicolás Luis; Moral Martínez, Luis del; Carmona Poyato, Ángel; Madrid-Cuevas, F.J.; Medina-Carnicer, R. (Elsevier, 2020)
      The present paper proposes a new non-optimal but unsupervised algorithm, called ICT-RDP, for generation of polygonal approximations based on the convex hull. Firstly, the new algorithm takes into account the convex hull ...
