Abstract: A method for reconstructing a three-dimensional image dataset from two-dimensional projection images includes recording the projection images using a collimator downstream of an X-ray source. A local Laplace filter is initially applied to the projection data of the projection images during the reconstruction using filtered back-projection. After this, high-frequency spikes arising in the Laplace-filtered projection data at boundaries to the image region are removed by a spike filter, and a global residual filter is applied. A fit parameter describing a fit function approximating the projection data characteristic in the uncorrected projection images inside the image region is determined based on at least marginal values of the projection data present at the boundaries. Next, following on from the use of the residual filter, an additive correction of the residual-filtered projection data in the image region is performed with the fit function scaled by a scaling factor.

Abstract: The present invention extends to methods, systems, and computer program products for cross-platform data visualizations using common descriptions. Embodiments of the invention provide mechanisms for simplifying software development and enhanced code reliability. A user interface, along with interactive and dynamic characteristics, can be described (programmatically and/or declaratively) independently of any specific device platform. User interface qualities can be described using a generic scene graph structure with attached behaviors. The generic scene graph can then be used to drive the user interface on any number of different computing platforms using platform specific (e.g., rendering, gesture recognition, etc.) sub-systems. Platform specific sub-systems can vary based on technologies that are used by the platform specific sub-systems. For example, rendering sub-systems can vary based on the technology used to render graphical data, such as, for example, Open GL, XAML, Direct X, Quartz, etc.

Abstract: In various implementations, methods and systems are disclosed for accurately selecting a targeted portion of a digital image. In one embodiment, a selection cursor having a central and a peripheral region is provided. The central region is used to force a selection or a deselection and therefore moving the central region over a portion of the image causes that portion of the image to be selected or deselected, respectively. The peripheral region of the cursor surrounds the central region and defines an area where a hybrid level set algorithm for both boundary detection and region definition, particularly a matting region, is performed. This provides highly accurate boundary detection and matting region selection within a narrowly-focused peripheral region and eliminates the need to subsequently designate a matting region and apply a matting algorithm to complex portions of an object selection.

For each pixel location in the desired image location, first and second best pixel values are calculated using the first and second set of candidate transformations, respectively, and the first and second best pixel values are blended to form an interpolated pixel.
