Local 3D Symmetry for Visual Saliency in 2.5D Point Clouds [chapter]

Ekaterina Potapova, Michael Zillich, Markus Vincze

The estimation of symmetry saliency maps is done on different scales to detect objects of various sizes. For evaluation a Winner-Take-All neural network is used to calculate attention points.  ...  ., attract attention, but complete objects do. Symmetry is a feature of many man-made and also natural objects and has thus been identified as a candidate for attentional operators.  ...  It means that after all relatively big objects were detected in cluttered scenes, smaller objects were ignored.  ...
