Abstract: An improved method for processing image voxel data representative of 3-dimensional images of a colon to remove the effects of tagged stool. The method uses parabolic curve intensity-gradient models at a transition between two material types as a function of the fraction of the two materials for each of a plurality of two-material type classes, including a gas-tissue transition model, a gas-stool transition model and a stool-tissue transition model. The voxels are classified into one of a plurality of substance classes including tagged stool, gas, tissue and unknown classes. The unknown class voxels are processed to classify the unknown class voxels into one of the two-material type classes. The two-material type class voxels are processed to determine the fractions of materials in each voxel. The intensity of the two-material type class voxels is then adjusted as a function of the fraction of the materials in the voxels.

Abstract: Avatars focal points are monitored as the Avatars move within a virtual environment to determine, statistically, where users are looking at in the virtual environment. The Avatar's focal point may be used to control a virtual brush that may paint the virtual environment in an attention monitoring function. A statistical distribution about the focal point is used to affect the coloration, and other known information about the virtual environment may be used to affect the statistics. As attention records from multiple users are collected, they may be overlaid to obtain a very accurate picture of how users are interacting with the virtual environment and with objects in the virtual environment. The attention monitoring function may generate a thermal overlay to the virtual environment to visually show where users tend to focus within the virtual environment. Users' attention on three dimensional and graphic objects may be monitored as well.

Abstract: Color transformation sample point identification is described. A subset of points from a superset of points representing a colorimetric relationship is identified. The subset of points defines an initial n-simplex with (n+1) points representing an approximation of the colorimetric relationship, where n represents a number of dimensions. An additional point from the superset of points is selected and added to the subset of points to replace the n-simplex with a set of at least two n-simplices. The additional point is selected such that a volume of an (n+1)-simplex formed by the (n+1) points of the initial n-simplex and the additional point is increased. An error value for the approximation is determined by calculating an error volume between the (n+1)-simplex and the superset of points.

Abstract: Embodiments enable a graphics processor to more efficiently process graphics and compositing processing commands. In certain embodiments, a client application submits client graphics commands to a graphics driver. The client in certain embodiments can notify a window server that client graphics commands have been submitted. In response, the window server can generate compositing processing commands and provide these commands to the graphics driver. Advantageously, a graphics processor can execute the client graphics commands while the window server generates compositing processing commands. As a result, processing resource can be used more efficiently.

The vector shape is scaled in synchronization with the desktop magnification level up to the convergence point whereby the vector shape is no longer scaled up once the convergence point is reached. The scaled vector shape is rasterized and displayed to an end user operating a computer.

Abstract: A system and method is disclosed for rendering an ultrasound volume. An external image of an ultrasound volume is generated. A fractional part of the external image corresponds to a fractional portion of the ultrasound volume. A composite image of the ultrasound is generated using the external image, wherein the fractional part of the external image is replaced with an internal image of the ultrasound volume fractional portion.
