. . . . "For the Panoptes building application the main detectable object of the smart cameras is the person. Therefore, three different image processing algorithms have been implemented, person detection, face detection and fall detection 5. After detecting some pertinent information, the smart camera describes what it \"observes\" by using the vocabulary defined in the WiseNET ontology, i.e., the smart camera extracts the knowledge of the scene. This addition of semantic meaning to what the camera \"observes\" is a problem known as semantic gap [39]." . . . . "2019-11-12T18:05:11+01:00"^^ . .
