摘要： The disclosure concerns a method for determining a change in position and orientation of an object using data from a synthetic aperture radar (SAR) with the following steps: acquiring a radar image containing the object; dividing the radar image into at least two subimages; acquiring short radar information comprising a first reflected pulse, which has been recorded by the radar and/or a quantity derived therefrom, the first reflected pulse having information about image data of the radar image; for the short radar information, performing an autofocus method which determines a change in distance for each of the at least two subimages; and determining the change in position and orientation of the object given for each point of the object by the respective change in distance of the corresponding subimage.

摘要： An animation wireframe is modified with three-dimensional (3D) range and color data having a corresponding shape surface. The animation wireframe is vertically scaled based on distances between consecutive features within the 3D range and color data and corresponding distances within the generic animation wireframe. For each animation wireframe point, the location of the animation wireframe point is adjusted to coincide with a point on the shape surface. The shape surface point lies along a scaling line connecting the animation wireframe point, the shape surface point and an origin point. The scaling line is within a horizontal point.

摘要： Optimal resilience to errors in packetized streaming 3-D wireframe animation is achieved by partitioning the stream into layers and applying unequal error correction coding to each layer independently to maintain the same overall bitrate. The unequal error protection scheme for each of the layers combined with error concealment at the receiver achieves graceful degradation of streamed animation at higher packet loss rates than approaches that do not account for subjective parameters such as visual smoothness.

摘要： According to MPEG-4's TTS architecture, facial animation can be driven by two streams simultaneously—text and Facial Animation Parameters. A Text-To-Speech converter drives the mouth shapes of the face. An encoder sends Facial Animation Parameters to the face. The text input can include codes, or bookmarks, transmitted to the Text-to-Speech converter, which are placed between and inside words. The bookmarks carry an encoder time stamp. Due to the nature of text-to-speech conversion, the encoder time stamp does not relate to real-world time, and should be interpreted as a counter. The Facial Animation Parameter stream carries the same encoder time stamp found in the bookmark of the text. The system reads the bookmark and provides the encoder time stamp and a real-time time stamp. The facial animation system associates the correct facial animation parameter with the real-time time stamp using the encoder time stamp of the bookmark as a reference.

摘要： A method and system for description of synthetic audiovisual content makes it easier for humans, software components or devices to identify, manage, categorize, search, browse and retrieve such content. For instance, a user may wish to search for specific synthetic audiovisual objects in digital libraries, Internet web sites or broadcast media; such a search is enabled by the invention. Key characteristics of synthetic audiovisual content itself such as the underlying 2d or 3d models and parameters for animation of these models are used to describe it. More precisely, to represent features of synthetic audiovisual content, depending on the description scheme to be used, a number of descriptors are selected and assigned values. The description scheme instantiated with descriptor values is used to generate the description, which is then stored for actual use during query/search. Typically, a user, to search for a needed synthetic audiovisual content initiates a query that is passed on to a search engine that then retrieves the candidate content from one or more databases whose description closely matches the query criteria specified by the user.

摘要： Methods and apparatus for rendering a talking head on a client device are disclosed. The client device has a client cache capable of storing audio/visual data associated with rendering the talking head. The method comprises storing sentences in a client cache of a client device that relate to bridging delays in a dialog, storing sentence templates to be used in dialogs, generating a talking head response to a user inquiry from the client device, and determining whether sentences or stored templates stored in the client cache relate to the talking head response. If the stored sentences or stored templates relate to the talking head response, the method comprises instructing the client device to use the appropriate stored sentence or template from the client cache to render at least a part of the talking head response and transmitting a portion of the talking head response not stored in the client cache, if any, to the client device to render a complete talking head response. If the client cache has no stored data associated with the talking head response, the method comprises transmitting the talking head response to be rendered on the client device.

摘要： Facial animation in MPEG-4 can be driven by a text stream and a Facial Animation Parameters (FAP) stream. Text input is sent to a TTS converter that drives the mouth shapes of the face. FAPs are sent from an encoder to the face over the communication channel. Disclosed are codes bookmarks in the text string transmitted to the TTS converter. Bookmarks are placed between and inside words and carry an encoder time stamp. The encoder time stamp does not relate to real-world time. The FAP stream carries the same encoder time stamp found in the bookmark of the text. The system reads the bookmark and provides the encoder time stamp as well as a real-time time stamp to the facial animation system. The facial animation system associates the correct facial animation parameter with the real-time time stamp using the encoder time stamp of the bookmark as a reference.
