摘要： A computer-implemented method for tracking one or more objects in a sequence of images includes generating a dictionary based on object locations in a first image included in the sequence of images. One or more object landmark candidates are identified in the sequence of images and a plurality of tracking hypothesis for the object landmark candidates are generated. A first tracking hypothesis is selected from the plurality of tracking hypothesis based on the dictionary.

摘要： A method and system for coronary artery detection in 3D cardiac volumes is disclosed. The heart chambers are segmented in the cardiac volume, and an initial estimation of a coronary artery is generated based on the segmented heart chambers. The initial estimation of the coronary artery is then refined based on local information in the cardiac volume in order to detect the coronary artery in the cardiac volume. The detected coronary artery can be extended using 3D dynamic programming.

摘要： Described are virtual AR interfaces for generating a virtual rotational interface for the purpose of controlling connected IoT devices using the inertial measurement unit (IMU) of a portable electronic device. The IMU control application enables a user of a portable electronic device to activate a virtual rotational interface overlay on a display and adjust a feature of a connected IoT product by rotating a portable electronic device. The device IMU moves a slider on the virtual rotational interface. The IMU control application sends a control signal to the IoT product which executes an action in accordance with the slider position. The virtual rotational interface is presented on the display as a virtual object in an AR environment. The IMU control application detects the device orientation (in the physical environment) and in response presents a corresponding slider element on the virtual rotational interface (in the AR environment).

摘要： The present invention provides an emergency starting device, including a first output end and a second output end, wherein the first output end is used for being connected to a positive electrode of an accumulator battery in an engine starting system and the second output end is used for being connected to a negative electrode of the accumulator battery; the device includes a super-capacitor, a controller and a DC-DC booster circuit, wherein the controller receives first electrical signal from the accumulator battery and electrically connects the super-capacitor and the accumulator battery to start the engine with energy stored in the super-capacitor when the first electrical signal changes suddenly, the DC-DC booster circuit increases the output voltage of the accumulator battery to charge the super-capacitor. The invention further provides an emergency starting method accordingly. By using the super-capacitor, the controller and the DC-DC booster circuit the invention fits in various severe environments and can start an engine in emergency permanently and effectively.
