      This paper presents an efficient graph-based algorithm for the segmentation of planar regions out of 3D range maps of urban areas. Segmentation of planar surfaces in urban scenarios is challenging because the data acquired ...

    • Segmentation of dynamic objects from laser data 

      Ortega Jiménez, Agustín Alberto; Andrade-Cetto, Juan (2011)
      Text en actes de congrés
      Accés obert
      We present a method to segment dynamic objects from high-resolution low-rate laser scans. Data points are tagged as static or dynamic based on the classification of pixel data from registered imagery. Per-pixel background ...
