      In this paper, we present an object pose estimation algorithm exploiting both depth and color information. While many approaches assume that a target region is cleanly segmented from background, our approach does not rely ...
    • 3D Reconstruction of Underwater Structures 

      Beall, Chris; Lawrence, Brian J.; Ila, Viorela; Dellaert, Frank (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2010)
      Environmental change is a growing international concern, calling for the regular monitoring, studying and preserving of detailed information about the evolution of underwater ecosystems. For example, fragile coral reefs ...
    • 3D Textureless Object Detection and Tracking: An Edge-based Approach 

      Choi, Changhyun; Christensen, Henrik I. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2012-10)
