Methods and apparatus for light-field imaging. Light-field camera designs are described that produce higher spatial resolution than conventional plenoptic camera designs, while trading-off the light-field's angular sampling density. This lower angular resolution may be compensated for by a light-field image processing method that inserts data synthesized by view interpolation of the measured light-field. In one embodiment, a light-field image processing method that performs three-view morphing may be used to interpolate the missing angular samples of radiance. The light-field camera designs may be implemented in hand-held light-field cameras that may capture a light-field with a single exposure. Some of the light-field camera designs are internal to the camera, while others are external to the camera. One light-field camera design includes a single, relatively large lens and an array of negative lenses that are placed in front of (external to) the main lens of a conventional camera.

An integrated system is described in which digital image data of a patient, obtained from a variety of image sources, including CT scanner, X-Ray, 2D or 3D scanners and color photographs, are combined into a common coordinate system to create a virtual three-dimensional patient model. Software tools are provided for manipulating the virtual patient model to simulation changes in position or orientation of craniofacial structures (e.g., jaw or teeth) and simulate their affect on the appearance of the patient. The simulation (which may be pure simulations or may be so-called “morphing” type simulations) enables a comprehensive approach to planning treatment for the patient. In one embodiment, the treatment may encompass orthodontic treatment. Similarly, surgical treatment plans can be created. Data is extracted from the virtual patient model or simulations thereof for purposes of manufacture of customized therapeutic devices for any component of the craniofacial structures, e.g., orthodontic appliances.

The present invention relates to a method of intelligent 2D and 3D object and scene modeling, transformation and manipulation and more particularly this invention relates to the field of computer modeling, virtual reality, animation and 3D Web streaming. The method uses attributed hypergraph representations (AHR) for modeling, transforming and manipulating objects. From one or more 2D views of a 3D object or scene, range information is first computed and then a triangular mesh model is constructed. The data structure is designed to handle the transformations on the representation corresponding to movements and deformations of the object. In an attributed hypergraph, the attributes associated with the hyperedges and the vertices facilitates modeling of various shapes with geometrical, physical or behavior features. As a hierarchical and generic representation, AHR enables pattern matching, recognition, synthesis and manipulation to be carried out at different resolution levels on different subsets depending on the context. Symbolic computation on knowledge represented in the format of attributed hypergraphs becomes straightforward. Given the features of a 3D object or scene, the procedure of constructing the AHR corresponds to the concept of functor in category theory, which maps one category to another one. The transformations of AHR are in the form of a set of operations defined on attributed hypergraphs, which stand for the motions and deformations of the object. This representation is applied to various modeling and manipulation tasks on 3D objects. The process of motion analysis of a 3D object is the task of extracting a sequence of AH operators from the AHR of the object. A 3D scene can be modeled by AHR and then altered / augmented with other 3D models, by which an augmented reality can be built. Given the AHR's of two different 3D shapes, 3D morphing may be accomplished by matching the two AHR's and then mapping the difference to a sequence of AH operators. Model based animation of an object can be accomplished by applying a set of AH operators to its AHR. The AHR method forms a data compression system for efficient web streaming over the Internet.

Icons can be combined to form toolbars such as those appearing on computer desktops and within application windows such as web browsers. Small icons are desired because desktop real estate is expensive. Small icons can be difficult to select or open because it can be hard to confirm which icon is indicated. An icon is indicated when the desktop cursor hovers over it. Altering the indicated icon provides good user feedback. Icons inside browser windows can be changed varying their size. Non-indicated icons can revert to a minimum size while an indicated one grows to a maximum size. Different images can be displayed for different sized icons, producing a more pleasing appearance. Alternatively, icons can be presented as display images produced by morphing two images together using morphing functions and icon weights. Morphing includes growing and shrinking as well as color changes, animating, and so forth.

The present invention provides a method for hierarchically decomposing a visual or audio object within an animation into plurality of objects which can be individually edited to achieve particular animation effects. For example, a graphical object may be decomposed into a plurality of graphical sub-objects, each of which is inherits an anchor point from the original object, or is given an original anchor point distinct from the original object. Each sub-object also includes a relative position for the sub-object relative to the anchor point. The path of the anchor point is combined with relative positions of the sub-objects to produce an animation for the object as a whole. This decomposition technique can greatly increase computational efficiency of an animation. It also provides for inheritance of attributes between objects and descendent sub-objects. The objects may support functions, or behaviors, such as morphing or motion blurring. The present invention additionally provides a flexible grouping operation to facilitate modifications to a group of objects. When a first type of modification is made to an attribute of an object in a group, this change is applied to corresponding attributes of other objects in the group. When a second type of modification is made to an attribute of an object in a group, the change only applies to the selected object or objects, and not to other objects in the group. The present invention allows objects to be manipulated on servers which are connected to a display via the Internet.

The invention proposes a method and apparatus for significantly improving the quality of voice morphing and guaranteeing the similarity of converted voice. The invention sets several standard speakers in a TTS database, and selects the voices of different standard speakers for speech synthesis according to different roles, wherein the voice of the selected standard speaker is similar to the original role to a certain extent. Then the invention further performs voice morphing on the standard voice similar to the original voice to a certain extent, in order to accurately mimic the voice of the original speaker, so as to make the converted voice closer to the original voice features while guaranteeing the similarity.

A method and apparatus for a novel adaptive aerostructure is presented that relies on certified aerospace materials and can therefore be applied in conventional passenger aircraft. This structure consists of a honeycomb material which cells extend over a significant length perpendicular to the plane of the cells. Each of the cells contains an inelastic pouch (or bladder) that forms a circular tube when the cell forms a perfect hexagon. By changing the cell differential pressure (CDP) the stiffness of the honeycomb can be altered. Using an external force or the elastic force within the honeycomb material, the honeycomb can be deformed such that the cells deviate from their perfect-hexagonal shape. It can be shown that by increasing the CDP, the structure eventually returns to a perfect hexagon. By doing so, a fully embedded pneumatic actuator is created that can perform work and substitute conventional low-bandwidth flight control actuators. It is shown that two approaches can be taken to regulate the stiffness of this embedded actuator.
