摘要： A computer-implemented method of providing a neural network for predicting a three-dimensional shape of an interventional device disposed within a vascular region, includes: training (S140) a neural network (140) to predict, from received X-ray image data (120) and received volumetric image data (110), a three-dimensional shape of the interventional device constrained by the vascular region (150). The training includes constraining the adjusting of parameters of the neural network such that the three-dimensional shape of the interventional device predicted by the neural network (150) fits within the three-dimensional shape of the vascular region represented by the received volumetric image data (110).

摘要： A depth image is used to obtain a three dimensional (3D) geometry of an object as an object mesh. The object mesh is obtained using an object shell representation. The object shell representation is based on a series of depth images denoting the entry and exit points on the object surface that camera rays would pass through. Given a set of entry points in the form of a masked depth image of an object, an object shell (an entry image and an exit image) is generated. Since entry and exit images contain neighborhood information given by pixel adjacency, the entry and exit images provide partial meshes of the object which are stitched together in linear time using the contours of the entry and exit images. A complete object mesh is provided in the camera coordinate frame.

摘要： A live facial recognition method includes capturing a zoom-out image of a face of a subject under recognition; and detecting a frame outside the face of the subject under recognition on the zoom-out image. The subject under recognition is determined to be a living subject when the zoom-out image includes no frame outside the face.

摘要： An information presentation device according to an embodiment includes a contour extraction unit, an abstraction processing unit, and a contour correction unit. The contour extraction unit extracts a contour of each structural object included in data showing a layout of a plurality of structural objects. The abstraction processing unit abstracts a contour of each structural object extracted by the contour extraction unit and draws the abstracted contour on a plane grid surface in which grid lines in two directions orthogonal to each other are drawn. The contour correction unit corrects, among contour lines to constitute a contour abstracted by the abstraction processing unit, a contour line deviating from both of the grid lines in the two directions so as to match a grid line in at least one direction of the grid lines in the two directions.

摘要： Methods and apparatus for treating a patient. The method includes acquiring a plurality of radio frequency (RF) signals with an ultrasound transducer, each RF signal representing one or more return echoes from a scan line of a pulse-mode echo ultrasound scan. A position of the ultrasound transducer corresponding to each of the acquired RF signals is determined, and a plurality of contour lines generated from the plurality of RF signals. The method estimates a 3-D shape and position of an anatomical feature, such as a joint of patient based on the generated contour lines and corresponding ultrasound transducer positions. An apparatus, or computer includes a processor and a memory with instructions that, when executed by the processor, perform the aforementioned method.

摘要： An image processing apparatus, which executes image processing for generating a virtual viewpoint image using a plurality of images captured by a plurality of imaging units that image an imaging space from different viewpoints, identifies a specific object among a plurality of objects inside the imaging space, and carries out image processing for generating the virtual viewpoint image on the plurality of objects inside the imaging space. The image processing apparatus executes the image processing on the identified specific object using images captured by more imaging units than in the image processing executed on other objects.

摘要： Provided is a system configured to obtain a set of images via a camera of the computing device, input the set of images into a neural network, and detect a target physical object with the neural network. The system may determine a contour of the target physical object and a first three-dimensional reconstruction of the target physical object. The system may generate a virtual representation and a virtual object based on attributes of the virtual representation, where a first attribute of the set of attributes includes the first three-dimensional reconstruction. The system may associate the virtual object with the virtual representation and displays the virtual object at pixel coordinates of a display that at least partially occlude at least part of the target physical object, where a position of the virtual object is computed based on the contour.
