      Forne, Christopher Jes (University of Canterbury. Electrical and Computer Engineering, 2007)
      This thesis deals with the problem of three dimensional scene reconstruction from multiple camera images. This is a well established problem in computer vision and has been significantly researched. In recent years some ...
    • 3-D seismic response of liquefaction-susceptible improved-soil deposits 

      Bradley, B.A.; Araki, K.; Ishii, T.; Saitoh, K. (University of Canterbury. Civil and Natural Resources Engineering, 2011)
      Numerous earthquakes occurring over the last five decades have illustrated the significant hazards posed by soil liquefaction. Recent observations have also illustrated the potential hazard mitigation that can be achieved ...
    • 3:5 - dimethyl xylose 

      Reeves, J. E. (University of Canterbury. Chemistry, 1949)
      Condensation of sugar alcohols with aldehydes was first observed by Meunier, 1888, who successfully formed a cyclic acetal from mannitol and benzaldehyde [diagram]. This condensation with aldehydes or ketones has since ...
    • 3D Articulated Model from a Stereo Camera 

      Sarjeant, Steve (University of Canterbury, 2006)
      The area of computer vision based motion capture and pose estimation has received much research interest. However, most proposed systems are tested in ideal conditions with heavily constricted movement and are thus less ...
