Application of Computer Vision in Security and Emergency Actions

There is a wide area of possible emergencies, from intentional to accidental. Mobile robots can be used in lot of them. To use mobile robots, we must have both reliable and high quality computer vision. This paper deals with different aspects of robot/computer vision applications in emergencies. Since there are a lot of difficulties in outdoor applications of robots, human expertise, human experience and human reactions can be non-replaceable. The best way to overcome problems is to implement the system with human operator in the command loop. It is called teleoperation. When medical task have to be performed, teleoperation is the only choice for now, because of complexity of actions. If the medical operation (surgery) need to be performed, then it is called telesurgery. To help doctors to be more sensitive of the distant scene, virtual reality can be used and development of tactile sensors can be vital. In the paper, a novel edge detector is presented. It is the intention to use it in mobile robots constructed for emergencies. Depending on which standard algorithm is used the performance of edge detector is improved by 10.41% to 53.36%. This is only a small step in image processing necessary for reactions in emergency situations. Edge detection is used to form matrix of distances between edges in image and robot. The use is in force feedback by visual input. Another possible application is in face recognition. If edges are better recognized, characteristic lines are to be better identified and, finally, face recognition more successful. Face recognition is very important in safety applications, but also in human-robot interaction. The last subject included in the paper is wavelet prediction of the motions in the robot teleoperation.
