Smooth video hopping for surveillance cameras
Takahiro Tsuda, Itaru Kitahara, Yoshinari Kameda, Yuichi Ohta · 2006
As more and more surveillance cameras are installed in towns and cities, they are going to be more open to the public, and people may want to see these videos. In such a scenario, people may find it difficult to understand which place they are seeing because it is almost impossible to remember which camera images are from which place and from which direction. This problem is particularly important when a viewer changes from one camera to another to see a scene from a different angle. This happens because the viewer sometimes does not understand the spatial relationship among cameras in a real space. When the image is instantly switched from one camera to the other, the viewer may feel disoriented because he/she has to place the location of the new camera in his/her mind to recognize what he/she is seeing. Therefore, a sophisticated camera switching method is needed that enables viewers understand how camera viewpoints change.
