    In this paper, an approach on immersive multiprojection visualization of manufacturing processes is proposed. It admits scenarios with dynamic components and allows virtual reality collaborative visualization among ...
  • Video segmentation based on motion coherence of particles in a video sequence 

    Silva, Luciano Silva da; Scharcanski, Jacob (2010)
    This work describes an approach for object-oriented video segmentation based on motion coherence. Using a tracking process based on adaptively sampled points (namely, particles), 2-D motion patterns are identified with an ...
