    摘要： Methods and systems for determining information about a vascular bodily lumen are described. An exemplary method includes generating an electrical signal, delivering the electrical signal to a plurality of excitation elements in the vicinity of the vascular bodily lumen, measuring a responsive electrical signal from a plurality of sensing elements in response to the delivered electrical signal, and determining a lumen dimension. Specific embodiments include generating a multiple frequency electrical signal. Another embodiment includes measuring plurality of responsive signals at a plurality of frequencies. Still other embodiments include using spatial diversity of the excitation elements. Yet other embodiments use method for calibration and de-embedding of such measurements to determine the lumen dimensions. Diagnostic devices incorporating the method are also disclosed, including guide wires, catheters and implants. The methods and systems described herein are advantageous as they do not include injecting a second fluid for the measurements.

    摘要： Pixels in a provided image for which the content has been provided in error are identified. This image content is processed to provide a version of the image wherein the error is at least partially concealed while also creating ancillary information regarding the errored pixel(s) and the spatial location to which such pixel(s) corresponds to thereby provide a record that describes which pixels in the image content were provided in error. An optional user-selectable option can permit displaying either of the aforementioned corrected version of the image wherein the error is at least partially concealed and a version of the image wherein the ancillary information is used to depict the errored pixel(s) such that provided-in-error pixels are readily distinguished from correctly-provided pixels.

    摘要： A video encoder (300) and method (400) for encoding video content that performs providing (402) transform coefficients and associated side information for macroblocks forming part of a frame of a video stream. Next the method processes (403) the transform coefficients and associated side information to obtain entropy coded information for the macroblocks. Slices are formed (404) from the entropy coded information, the slices having slice widths that are adaptively adjusted based upon the non-uniformity of video content of the frame.

    摘要： A method and apparatus for determining the quality of a block match for a candidate motion vector in a video encoder system using motion vectors representing the difference in coordinates of a macroblock of data in a current frame of video data and coordinates of a related macroblock of data in a reference frame of video data. The method can include defining a search pattern, searching a region based on the search pattern for a candidate motion vector for evaluation, calculating a difference metric, calculating a bias based on the difference between a predictor motion vector and a candidate motion vector, determining a modified difference metric by adding the difference metric to the bias, and defining a final motion vector based on the modified difference metric.
