  • Agrupamiento por similitud de imagenes mediante Árbol de Expación Mínimo y Soft Heap 

    López Del Alamo, Cristian José; Fuentes Pérez, Lizeth Joseline; Romero Calla, Luciano Arnaldo (Pontificia Universidad Católica de Valparaíso, 2013-11-11)
    En la presente investigación se propone un enfoque novedoso para extraer características distintivas de imagenes basado en el modelo de color HSV y filtros wavelets, con la finalidad de hacer un agrupamiento de imágenes ...
  • Parallelization of the Algorithm K-means Applied in Image Segmentation 

    López Del Alamo, Cristian José; Romero Calla, Luciano Arnaldo; Fuentes Pérez, Lizeth Joseline (International Journal of Computer Applications, 2014-01-01)
    Algorithm k-means is useful for grouping operations; however, when is applied to large amounts of data, its computational cost is high. This research propose an optimization of k-means algorithm by using parallelization ...
  • 3D mesh interest point detection using GISIFs and heat diffusion 

    López Del Alamo, Cristian José; Hurtado, Jan; Coaquira, Madeley (Computing Conference (CLEI), 2015 Latin American, 2015-10-19)
    To facilitate processing of 3D objects is common to use high-level representations. The interest points are one of them. An interest point should possess a distinctive feature regarding its locality and should be stable ...
  • Efficient approach for interest points detection in non-rigid shapes 

    López Del Alamo, Cristian José; Romero Calla, Luciano Arnaldo; Fuentes Pérez, Lizeth Joseline (Computing Conference (CLEI), 2015 Latin American, 2015-12-17)
    Due to the increasing amount of data and the reduction of costs in 3D data acquisition devices, there has been a growing interest, in developing efficient and robust feature extraction algorithms for 3D shapes, invariants ...
