    摘要: An electronic device is provided including a processor, a communications interface coupled to the processor, a memory coupled to the processor, and a module saved in the memory. The module configures the processor to receive a first communications packet from a remote device via the communications interface including information useful for estimating a clock offset of the remote device, and determine an upper bound of the clock offset of the remote device with respect to the electronic device based on the information.

    摘要: A method for constructing a georeferencing-enabled camera model and its deployment in georeferencing targets located in video sequences due to a single video camera. A video surveillance camera is modeled by a collection of rays converging at a virtual camera point and the retina resolution cell coordinates associated with those rays wherein the ray equations are first established, in the course of a calibration process, for a given camera view, with the aid of other views of the same video surveillance camera, as necessary, and using such a model for mapping image coordinates to terrain coordinates and vice versa in the intended view or its adaptation for use in other views of the same video surveillance camera.

    摘要: A method and system for providing remote access to a state of an application is provided. The method comprises executing an application program at a server computer for performing an application associated therewith. At a client computer connected to the server computer via a communication network a remote access program is executed for providing remote access to a state of the performed application. At the client computer a client difference program having encoded data indicative of a change of a state of the application last received from the server computer is generated and transmitted to the server computer. At the server computer the client difference program is executed for determining an updated state of the application and a server difference program having encoded a difference between the updated state of the application and the state of the application last sent to the client computer is generated. The server difference program is then transmitted to the client computer and at the client executed for updating the state of the application last received from the server computer. Display data indicative of the updated state of the application last received from the server computer are generated and displayed in a human comprehensible fashion on a display.
