Abstract: Scene rendering apparatus for rendering a scene from a 3D scene description data, configured to derive, from the 3D scene description data, first data defining a 3D object and second data defining an animation of the object and trigger condition information which defines a condition for viewing position and/or viewing orientation. Additionally, the scene rendering apparatus is configured to check whether the condition for viewing position and/or viewing orientation is met, and responsive to the condition for viewing position and/or viewing orientation being met, trigger the animation of the object.

Abstract: Scene description data having first data defining a 3D object and second data triggering an animation of the 3D object. The second data triggers an application of the animation to the 3D object and has a parameter discriminating between several animation modes of the application.

Abstract: The A method of augmenting a view of a real-world environment with a view of a volumetric video object on a user device is disclosed . The method includes determining a current pose information (CPI) indicating a current pose of the view of the real-world environment and a desired pose of the volumetric video object in the real-world environment. The method further includes sending the CPI to a remote server. The method further includes receiving a rendered view of the volumetric video object that has been rendered in accordance with the CPI from the remote server. The method also includes augmenting the view of the real-world environment by at least mapping the rendered view of the volumetric video object onto a planar mapping surface arranged according to the desired position of the volumetric video object.

Abstract: A medical imaging device, comprising a illumination unit, can be configured to illuminate a tissue area with light from a first spectral range, comprising a range of visible wavelengths, and with light from a second spectral range, which is different from the first spectral range, an imaging unit, configured to detect light from the first spectral range and to generate a first image of the tissue area on the basis of the detected light from the first spectral range and furthermore configured to detect light from the second spectral range and to generate a second image of the tissue area on the basis of the detected light from the second spectral range, and a superposition unit, configured to generate a superimposed image on the basis of the first and second image in such a way that, in the superimposed image, on the basis of a visual highlighting, it is possible to identify whether and where the tissue area comprises highlight regions which are characterized by an increased emission of light from the second s

Abstract: An apparatus for performing 3D estimation on the basis of pictures of at least two different views includes a hypotheses provider, a similarity measure calculator, and a 3D information determiner. The hypotheses provider locally determines 3D information hypotheses for positions of a current picture of a first view on the basis of a pre-estimate which associates a 3D information estimate to each position of a picture of the first view. The similarity measure calculator calculates, for each position of the current picture of the first view, a hypotheses of the respective position by measuring a similarity between a region similarity measure for each of the 3D information of the current picture of the first view at the respective position and a corresponding region of a second view at a position displaced relative to the respective position by a respective 3D information hypothesis.

Abstract: A method for generating 3D-information from multiple images showing a 3D scene from multiple perspectives has: providing at least two hypotheses for the 3D-information; performing a multi-hypotheses test by matching the at least two hypotheses to the multiple images and determining a test-result hypothesis that fulfills a particular matching criterion; updating the test-result hypothesis by varying a parameter set of the test-result hypothesis to further improve the matching criterion or another criterion; and determining the 3D-information on the basis of the parameter set of a resulting hypothesis provided by the action of updating the test-result hypothesis. A corresponding computer readable digital storage medium and a 3D-information generator are also described. Further embodiments perform a correspondence analysis between projections of spatio-temporal objects (STO) in multiple images to select a particular spatio-temporal object on the basis of said correspondence analysis.
