    摘要: A method and apparatus for automatically detecting stent struts in an image is disclosed whereby the inner boundary, or lumen, of an artery wall is first detected automatically and intensity profiles along rays in the image are determined. In one embodiment, detection of the lumen boundary may be accomplished, for example, by evolving a geometric shape, such as an ellipse, using a region-based algorithm technique, a geodesic boundary-based algorithm technique or a combination of the two techniques. Once the lumen boundary has been determined, in another embodiment, the stent struts are detected using a ray shooting algorithm whereby a ray is projected outward in the OCT image starting from the position in the image of the OCT sensor. The intensities of the pixels along the ray are used to detect the presence of a stent strut in the image.

    摘要: Some embodiments provide a method of combining multiple streams of data packets into a single combined stream in a manner that facilitates accurate estimation of bandwidth of a connection over a network between two devices. When combining the streams into the combined stream, the method associates a set of packets from a first stream and a reference packet from a second stream to form a longer sequence of packets in the combined stream. The method sends the combined stream from a first device to a second device so that the second device can estimate the bandwidth of the connection between the first and second devices based on the inter-arrival times of the packets in the sequence of packets.

    摘要: A method and apparatus for adapting transmission to improve quality of service in a mobile wireless device that includes an application processor and a transceiver. An application service connection is established between the mobile wireless device and a remote device. The transceiver in the mobile wireless device monitors real time properties of a radio frequency access link that transports packets for the application service between the mobile wireless device and a wireless communication network. The transceiver provides local feedback to the application processor of updated values of the monitored real time properties. The application processor adjusts packet data generation and transmission in response to the updated values to manage quality of service for the application service connection. Packet data transmission adjustment includes active management of queues in the transceiver by the application processor, selectively dropping packets based on packet classifications and the local feedback information provided to the application processor.

    摘要: The present invention discloses a method and an apparatus for eliminating frequency-domain interference signals, and relates to communication technologies. The method includes: multiplying a frequency-domain channel estimation value by a frequency-domain interference signal to obtain a frequency-domain received interference signal; and subtracting the frequency-domain received interference signal from the frequency-domain received signal to obtain the frequency-domain received signal free of interference. The apparatus includes a multiplying module and a subtracting module. A frequency-domain equalizer includes an interference signal obtaining module and an interference signal eliminating module. The technical solution provided herein eliminates interference signals in the frequency domain, and saves the calculation load in contrast with elimination of time-domain interference signals.
