  • Patent number: 10368843
    Abstract: An ultrasonic diagnostic imaging system produces an image of shear wave velocities by transmitting push pulses to generate shear waves. A plurality of tracking lines are transmitted and echoes received by a focusing beamformer adjacent to the location of the push pulses. The tracking lines are sampled in a time-interleaved manner. The echo data acquired along each tracking line is processed to determine the time of peak tissue displacement caused by the shear waves at points along the tracking line, and the times of peaks at adjacent tracking lines compared to compute a local shear wave velocity. The resultant map of shear wave velocity values is color-coded and displayed over an anatomical image of the region of interest.

  • Patent number: 10368051
    Abstract: A 3D-HEVC inter-frame information hiding method based on visual perception includes steps of information embedding and information extraction. In the step of information embedding, the human visual perception characteristic is considered, stereo salient images are obtained by a stereo image salient model, and the stereo salient images are divided into salient blocks and non-salient blocks with an otsu threshold. The coding quantization parameters are modified according to different modulation rules for different regions. Then, based on the modified quantization parameters, the coding-tree-units are coded to complete the information embedding. In the step of information extraction, no original video is needed, no any side information needs to be transmitted, and the secret information can be blindly extracted.

Triangles are formed from the tiles of the destination mesh. A forward map is generated based on the triangles and the backward map. The forward map maps points from the source mesh to pixels in the destination image. A point from the source mesh is identified that corresponds to a pixel of a feature of interest. The forward map is applied to this point to locate a pixel in the destination image. This pixel corresponds to the location of the feature in the destination image.

  • Patent number: 9792683
    Abstract: A camera mounted on or for a vehicle has camera rotational parameters ?, ?, ? and camera translational parameters xc, yc, zc in a camera image coordinate system, and the vehicle has a vehicle coordinate system. A method for online or on-the-fly calibration of the camera involves two independent steps, namely while the vehicle is moving relative to the ground, calibrating the camera rotational parameters using a parallel geometrical calibration process, and calibrating at least some of the camera translational parameters xc, yc independently of the camera rotational parameters.

  • Patent number: 9762846
    Abstract: Various technologies described herein pertain to creation of an output hyper-lapse video from an input video. Values indicative of overlaps between pairs of frames in the input video are computed. A value indicative of an overlap between a pair of frames can be computed based on a sparse set of points from each of the frames in the pair. Moreover, a subset of the frames from the input video are selected based on the values of the overlaps between the pairs of the frames in the input video and a target frame speed-up rate. Further, the output hyper-lapse video is generated based on the subset of the frames. The output hyper-lapse video can be generated without a remainder of the frames of the input video other than the subset of the frames.

  • Patent number: 9724538
    Abstract: When delineating anatomical structures in a medical image of a patient for radiotherapy planning, a processor (18) detects landmarks (24) in a low-resolution image (e.g., MRI or low-dose CT) and maps the detected landmarks to reference landmarks (28) in a reference contour of the anatomical structure. The mapped landmarks facilitate adjusting the reference contour to fit the anatomical structure. The adjusted reference contour data is transformed and applied to a second image using a thin-plate spline, and the adjusted high-resolution image is used for radiotherapy planning.

  • Patent number: 9691127
    Abstract: In an example embodiment a method, apparatus and computer program product are provided. The method includes calculating directionality values for pixels of a first image and pixels of a second image, where a directionality value for a pixel is calculated based on gradient differences between the pixel and a plurality of neighboring pixels. The method includes determining a plurality of similarity values between the first image and the second images for a plurality of alignment positions of the first image and the second image based on the directionality values for the pixels of the first image and the directionality values for corresponding pixels of the second image. The method further includes selecting an alignment position from among the plurality of alignment positions for aligning the first image and the second image based on comparison of the plurality of similarity values.

  • Patent number: 9659368
    Abstract: Systems and methods for generating a medical image of a subject that includes functional information. First, two medical images are acquired. One is weighted based on functional information reflecting physiological functions of the subject and the other weighted based on anatomic information of the subject. A difference image between the two images are generated. By subjecting the difference image and the second image to a localized kernel, a local similarity image is generated. Using the local similarity image, an improved difference image is generated. Lastly, by subtracting the improved difference image from the first image, an enhanced medical image that retains the functional information reflecting physiological functions of the subject is generated.

  • Patent number: 9651662
    Abstract: A method for interventional navigation using 3D contrast-enhanced ultrasound (CEUS) imaging includes acquiring a reference 3D CEUS volume and tracking information during a useful lifetime of a contrast enhancement agent administered to the anatomy. Real-time tracked tissue images are acquired during the interventional procedure. In addition, a corresponding CEUS multiplanar reconstruction (MPR) for at least one of the acquired real-time tracked tissue images is generated. At least one of the acquired real-time tracked tissue images is displayed along with the corresponding CEUS MPR. The displayed real-time tracked tissue image includes at least an image of the instrument within the desired portion of the anatomy and the CEUS MPR corresponds to the displayed real-time tracked tissue image. Thus, the contrast enhanced image information and tissue image information are concurrently display for the interventional navigation at least subsequent to the expiration of the contrast enhancement useful lifetime.

  • Patent number: 9648211
    Abstract: Methods and systems for automatically synchronizing videos acquired via two or more cameras with overlapping views in a multi-camera network. Reference lines within an overlapping field of view of the two (or more) cameras in the multi-camera network can be determined wherein the reference lines connect two or more pairs of corresponding points. Spatiotemporal maps of the reference lines can then be obtained. An optimal alignment between video segments obtained from the cameras is then determined based on the registration of the spatiotemporal maps.
