Abstract: Methods, systems, and techniques for tagless tracking of an object-of-interest are disclosed. Image and non-image data are generated across a plurality of camera-specific regions, and the object-of-interest is tracked over a global map formed as a composite of these regions.

Abstract: Alias capture to support searching for an object-of-interest is disclosed. A method includes capturing, using a camera with a defined field of view, video image frames that include a moving object-of-interest. The method also includes tracking the object-of-interest over a period of time starting when the object-of-interest enters the field of view and ending when the object-of-interest exits the field of view. The method also includes detecting, at a point in time in-between the start and end of the period of time of the tracking, a threshold exceeding change in an appearance of the object-of-interest. The method also includes creating, before the end of the period of time of the tracking, a new object profile for the object-of-interest in response to the detecting of the threshold exceeding change.

Abstract: A computer-implemented method for detecting a person in a room using a sensor, such as a radar sensor or depth cameras is provided. The method can be used to detect sleeping persons in a publically accessible location to prevent loitering. Furthermore, the method can be used to identify which rooms amongst a plurality of rooms are occupied, for example changing rooms.

Abstract: A method and system for controlling a passage from a secured location to an unsecured location based on presence detection of the unsecured location, including: a radar system in the secure location configured to transmit radar signals to and receive radar signals from the unsecured location; on determination of the presence, by the radar system, of a first person in the unsecured location proximate to the passage, providing an alert. The determination of the presence of the first person in the unsecured location may be triggered by a second person in the secured location moving proximate to the exit or by the second person in the secured location requesting to exit through the passage.
