Semantic description in stereo video content for surveillance applications
The use of a stereo camera in surveillance applications adds information about the in depth position of the object being monitored. Thus, stereo videos can help extract semantic information about a person or object movement direction, not only on the image plane, but also in depth space. This paper describes a method that performs semantic labeling of movement direction in stereo videos along the horizontal and vertical axes and also along the depth axis when disparity information is available. A method that that extracts information about whether two or more objects are approaching or moving away is also presented.
