摘要： A method and system for creating three-dimensional models of implant-bearing dental arches, and other anatomical fields of view, employs three-dimensional scanning means to capture images of an anatomical field of view wherein there have been positioned (and preferably affixed to an anatomical feature) one or more three-dimensional recognition objects having a known geometry, such as a pyramid or a linked grouping of spheres. Image processing software is employed to locate and orient said recognition objects as reference data for stitching multiple images and thereby reconstructing the scanned field of view. Recognition objects placed in areas of low feature definition enhance the accuracy of three-dimensional modeling of such areas.

摘要： A method for determining the pose of a camera (22, 32) relative to a real environment (40) comprises the following steps: recording at least one image (50) of a real environment by means of a camera (22, 32), wherein the image includes at least one part of a real object (41), carrying out a tracking method which evaluates information with regard to correspondences between features associated with the real object (41) and corresponding features of the real object (41) such as is contained in the image (50) of the real environment, in order to draw conclusions about the pose of the camera (22, 32), determining at least one parameter of an environment situation, and carrying out the tracking method depending on the at least one parameter. The method can analogously also be applied in a method for recognizing an object of a real environment in an image recorded by a camera.

摘要： An electronic program guide is displayed in a manner that does not interfere with the presentation of program content. Thus, the electronic program guide is displayed on a first display surface (304,704) which is distinct from a second display surface (308,504). For example, the receiver may output altered 3D output signals with one frequency of the output signal containing EPG data and a second frequency of the 3D output signal containing visual content from the broadcast program. Headsets (304,308) are worn by the viewers so that each viewer may either see the program or see the electronic program guide. In another embodiment, an EPG is periodically inserted into the video stream during predetermined frames, which are then captured and held by a synchronized headset. In another embodiment, an EPG image is output through a projector onto a projection surface (704).

摘要： Systems and methods that acquire digital slides and other large images and store these images into commercially available PACS systems using DICOM-standard messaging are provided. A digital slide or other large two-dimensional image is acquired and each separate resolution level of the digital slide or large image is divided into a series of regions that are each identified as a DICOM image. All of the regions at the same resolution in the digital slide or other large image are collectively identified as a DICOM series. A plurality of DICOM series, representing multiple resolution levels in a digital slide are collectively identified and stored as a DICOM study.

摘要： Systems and methods for aligning objects in object sets are provided. An object set has objects that are in a corresponding image in a plurality of images. For each respective object in a first object set, a corresponding object group is constructed that contains the respective object, thereby constructing a plurality of object groups. Similarity metrics are computed between object groups and objects in objects sets in order to assign the objects to object groups. The object groups are then refined in order to align objects in the object sets.

摘要： A method for performing image processing for computer-aided eye-surgery, said method comprising:
acquiring a reference image of the eye;
enriching said reference image by inserting additional context information which are helpful for a surgeon when performing the eye surgery;
registering said reference image with a real time image of the eye; and
overlaying the context information over the real time image of the eye based on a tracking of the eye movement such that the context information is displayed at the same position despite a movement of the eye.
