• openAccess   On hidden Markov models and cyclic strings for shape recognition 

      Palazón González, Vicente; Marzal Varó, Andrés; Vilar Torres, Juan Miguel Elsevier (2014)
      Shape descriptions and the corresponding matching techniques must be robust to noise and invariant to transformations for their use in recognition tasks. Most transformations are relatively easy to handle when contours ...
    • openAccess   On the Dynamic Time Warping of Cyclic Sequences for Shape Retrieval 

      Palazón González, Vicente; Marzal Varó, Andrés Elsevier (2012)
      In the last years, in shape retrieval, methods based on Dynamic Time Warping and sequences where each point of the contour is represented by elements of several dimensions have had a significant presence. In this approach ...
    • openAccess   Speeding up the cyclic edit distance using LAESA with early abandon 

      Palazón González, Vicente; Marzal Varó, Andrés Elsevier (2015)
      The cyclic edit distance between two strings is the minimum edit distance between one of this strings and every possible cyclic shift of the other. This can be useful, for example, in image analysis where strings describe ...
