摘要:
A system and process for automatically learning a reliable color-based tracking system is presented. The tracking system is learned by using information produced by an initial object model in combination with an initial tracking function to probabilistically determine the configuration of one or more target objects in a temporal sequence of images, and a data acquisition function for gathering observations relating to color in each image. The observations gathered by the data acquisition function include information that is relevant to parameters desired for a final color-based object model. A learning function then uses probabilistic methods to determine conditional probabilistic relationships between the observations and probabilistic target configuration information to learn a color-based object model automatically tailored to specific target objects. The learned object model is then used in combination with the final tracking function to probabilistically locate and track specific target objects in one or more sequential images.
摘要:
The present invention is embodied in a system and process for automatically learning a reliable tracking system. The tracking system is learned by using information produced by an initial object model in combination with an initial tracking function, and a data acquisition function for gathering observations about each image. The initial tracking function probabilistically determines the configuration of one or more target objects in a temporal sequence of images. The observations gathered by the data acquisition function include information that is relevant to parameters desired for a final object model. These relevant observations may include information such as the color, shape, or size of a tracked object, and depend on the parameters necessary to support the final tracking function. A learning function based on a learning method such as, for example, neural networks, Bayesian belief networks (BBN), discrimination functions, decision trees, expectation-maximization on mixtures of Guassians, probability distribution functions (PDF), estimation through moment computation, PDF estimation through histograms, etc., then uses the observations and probabilistic target location information to probabilistically learn an object model automatically tailored to specific target objects. The learned object model is then used in combination with the final tracking function to probabilistically locate and track specific target objects in one or more sequential images.

A handle-operating mechanism for a circuit breaker includes a rotary operating handle for opening and closing a main-circuit contact of a circuit breaker, a rotating gear operably connected to the operating handle and having a first engaging device, and a contact opening-and-closing mechanism having a toggle gear meshing with the rotating gear. A clutch gear is connected to the operating handle to be interposed between the operating handle and the rotating gear, and has a second engaging device. An idle stroke is formed such that when the circuit breaker is turned on, the operating handle runs idly after rotation of the operating handle has been started and before the second engaging device engages the first engaging device to drive the rotating gear for actuating the toggle gear.

A U-shaped magnetic plate is positioned on the side of a movable contact shoe opposite to a fixed contact shoe, and the tips of the respective legs of the magnetic plate face via a gap the movable contact shoe in a closed condition of the movable contact shoe. A magnetic plate is attached to the surface of the movable contact shoe at the side of the fixed contact, so that the magnetic plates form a closed magnetic circuit surrounding the movable contact shoe. If a high current, such as short circuit current, flows, a magnetic flux passing through the closed magnetic circuit induces an attractive force between the upper end surfaces of the U-shaper magnetic plate and the end surface of the magnetic plate. Accordingly, the movable contact shoe is rapidly opened to quickly interrupt the current, before a signal from an overcurrent trip apparatus operates an opening and closing mechanism. The opening speed of the movable contact shoe is increased when high current flows.

An inter-network remote control system is described that enables remote control of computing devices via two or more disparate data communications networks. In various embodiments, the inter-network remote control system receives a message from a mobile device via a first network, transforms the received message so that it can be relayed via a second network, and forwards the transformed message via the second network to a target computing device to cause that device to be controlled remotely.

A multi-user computer system may distribute user windows across multiple monitors, some of the user windows may span two or more monitors, and some user windows may share a monitor. Each user window may be associated with a set of user input devices for each user. The user window configuration may be changed on the fly by an administrative user, who may reposition, rotate, scale, or perform other changes to the windows. Some embodiments may include a rule stack that may apply different levels of rules in succession to allocate user windows.

A range of unified software authoring tools for creating a talking paper application for integration in an end user platform are described herein. The authoring tools are easy to use and are interoperable to provide an easy and cost-effective method of creating a talking paper application. The authoring tools provide a framework for creating audio content and image content and interactively linking the audio content and the image content. The authoring tools also provide for verifying the interactively linked audio and image content, reviewing the audio content, the image content and the interactive linking on a display device. Finally, the authoring tools provide for saving the audio content, the video content and the interactive linking for publication to a manufacturer for integration in an end user platform or talking paper platform.

Users can send short message service (SMS) communication with the purpose of the communication being implied therein. An SMS broker described herein can derive the implied purpose by parsing the communication at least in part according to defined set of rules of syntax and in light of a current context within which the communication was received. In one aspect, the communication is brokered via the SMS broker and it may be intended as a message to be sent to another user identified by a moniker, such as their e-mail alias, which has the advantage of avoiding the need to store phone numbers on memory-constrained devices. In another aspect, the communication is a request for user data of other users also identified in the request by a simple moniker such as their e-mail alias. Additionally, a user can also send a communication intended to update their own user information such as their current location, availability and so on.

System and method for estimating and tracking an orientation of a user's face by combining head tracking and face detection techniques. The orientation of the face, or facial pose, can be expressed in terms of pitch, roll and yaw of the user's head. Facial pose information can be used, for example, to ascertain in which direction the user is looking. In general, the facial pose estimation method obtains a position of the head and a position of the face and compares the two to obtain the facial pose. In particular, a camera is used to obtain an image containing a user's head. Any movement of the user's head is tracked and the head position is determined. A face then is detected on the head and the face position is determined. The head and face positions then are compared.
