      Video segmentation is an important building block for high level applications, such as scene understanding and interaction analysis. While outstanding results are achieved in this field by the state-of-the-art learning and ...
    • Time consistent estimation of End-effectors from RGB-D data 

      Lin, Xiao; Casas Pla, Josep Ramon; Pardàs Feliu, Montse (Springer, 2015)
      Conference lecture
