A method for generating a tree structure representation of a generalized graph structure for display includes the more important links in the representation. Usage parameters are referenced in generating the tree structure from the generalized graph structure. Frequency, recency, spacing of accesses, and path information are exemplary types of usage parameters. A breadth-first or depth-first traversal of the graph references usage parameters associated with each node or link. The usage parameters which are associated with each node are referenced in order to determine the visitation order. The visitation order is determined by visiting the highest used nodes or links first. A method of displaying the tree structure references the usage parameters to determine the positioning of the nodes in the layout of the tree structure. In a preferred embodiment, the root node is positioned in the center of the layout. In one example, sibling nodes are spread out on links which emanate radially about their parent. The highest-used sibling nodes can be placed farthest apart from each other so as to achieve optimal separation so that they have the most growth space. The lowest-used nodes are then placed in the remaining space between the high-usage nodes. In another example, sibling nodes are positioned at the same radius from the root node. Each leaf node in the hierarchy is assigned the same amount of angular space. The layout angle of each node is a function of the ranking of the node's usage parameter relative to its siblings. Derived usage parameters such as need probability, cocitation clustering, or functions of both node and link usages can alternatively be referenced.

A system for estimating motion parameters corresponding to a user. The system may generally include a receiver operable to receive a signal from an external source, an inertial sensor operable to be coupled with the user and arbitrarily oriented relative to the direction of user motion for generation of a signal corresponding to user motion, and a processing system in communication with the receiver and inertial sensor. The processing system can be operable to utilize the receiver signal to estimate a first parameter corresponding to a first motion parameter type, utilize the inertial sensor signal to estimate a second parameter corresponding to a second motion parameter type, generate a user-specific motion model to correlate the first parameter type and second parameter type using at least the first and second estimated parameters, utilize the inertial sensor signal to estimate a third parameter corresponding to the second parameter type, and utilize the motion model and the third parameter to estimate a fourth parameter corresponding to the first parameter type independent of the receiver signal.

A method for extending functionality of a compiler includes: receiving a first source file written in a language that supports multiple system types, wherein the first source file includes a plurality of source constructs associated with parameter types of the multiple type systems; annotating each of the plurality of source constructs with the type system from one of the multiple type systems and precise parameter type to which its associated type system belongs; retrieving type system rules corresponding to each type system referred to in the first source file from a type system loader; verifying, using the type system rules, that instances of use of variables, expressions, and methods in the first source file are appropriate with respect to the type system of annotated types associated with the source constructs; and compiling the first source file to produce a second source file including type information retained from the first source file.

A real-time approximately 360 degree image correction system and a method for alleviating distortion and perception problems in images captured by omni-directional cameras. In general, the real-time panoramic image correction method generates a warp table from pixel coordinates of a panoramic image and applies the warp table to the panoramic image to create a corrected panoramic image. The corrections are performed using a parametric class of warping functions that include Spatially Varying Uniform (SVU) scaling functions. The SVU scaling functions and scaling factors are used to perform vertical scaling and horizontal scaling on the panoramic image pixel coordinates. A horizontal distortion correction is performed using the SVU scaling functions at at least two different scaling factors. This processing generates a warp table that can be applied to the panoramic image to yield the corrected panoramic image. In one embodiment the warp table is concatenated with a stitching table used to create the panoramic image.
