  • Patent number: 8638846
    Abstract: Systems and methods for encoding/decoding a video stream. Animated talking heads are coded using partial offline encoding, multiple video streams, and multiple reference frames. The content of a face animation video that is known beforehand is encoded offline and the remaining content is encoded online and included in the video stream. To reduce bit rate, a server can stream multiple video sequences to the client and the video sequences are stored in the client's frame store. The server sends instructions to play a particular video sequence instead of streaming the particular video sequence. Multiple video streams can also be streamed to the client. Positional data and blending data are also sent to properly position one video stream relative to another video stream and to blend one video stream into another video stream.

  • Publication number: 20140023237
    Abstract: A method of improving the lighting conditions of a real scene or video sequence. Digitally generated light is added to a scene for video conferencing over telecommunication networks. A virtual illumination equation takes into account light attenuation, lambertian and specular reflection. An image of an object is captured, a virtual light source illuminates the object within the image. In addition, the object can be the head of the user. The position of the head of the user is dynamically tracked so that an three-dimensional model is generated which is representative of the head of the user. Synthetic light is applied to a position on the model to form an illuminated model.

  • Publication number: 20130228941
    Abstract: A system and a method for promoting improved air flow through a cooling tower and reduced inner air pressure losses caused by rain in the rain zone of a cooling tower. Aerodynamic modules are mounted on the lower edge of the cooling tower shell in order to deflect the downward-flowing air about the lower edge of the tower shell and into the rain zone. The aerodynamic modules can be modularly mounted, can be replaced, and do not affect the statics of the tower shell. Aerodynamic modules can also be built on the base area to deflect the incoming air over any obstacles. Troughs or dripping elements can also promote flow by reducing the rain falling in an outer area.

  • Patent number: 8135202
    Abstract: An automated method and system for analyzing a digital image of a biopsy to determine whether the biopsy is normal or abnormal, i.e., exhibits some type of disease such as, but not limited to, cancer. In the method and system, a classifier is trained to recognize well formed nuclei outlines from imperfect nuclei outlines in digital biopsy images. The trained classifier may then be used to filter nuclei outlines from one or more digital biopsy images to be analyzed, to obtain the well formed nuclei outlines. The well formed nuclei outlines may then be used to obtain statistics on the size or area of the nuclei for use in determining whether the biopsy is normal or abnormal.

  • Patent number: 8135652
    Abstract: Disclosed is an improved technique for training a support vector machine using a distributed architecture. A training data set is divided into subsets, and the subsets are optimized in a first level of optimizations, with each optimization generating a support vector set. The support vector sets output from the first level optimizations are then combined and used as input to a second level of optimizations. This hierarchical processing continues for multiple levels, with the output of each prior level being fed into the next level of optimizations. In order to guarantee a global optimal solution, a final set of support vectors from a final level of optimization processing may be fed back into the first level of the optimization cascade so that the results may be processed along with each of the training data subsets.

  • Patent number: 8086464
    Abstract: 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.

  • Patent number: 7990384
    Abstract: A system and method for generating photo-realistic talking-head animation from a text input utilizes an audio-visual unit selection process. The lip-synchronization is obtained by optimally selecting and concatenating variable-length video units of the mouth area. The unit selection process utilizes the acoustic data to determine the target costs for the candidate images and utilizes the visual data to determine the concatenation costs. The image database is prepared in a hierarchical fashion, including high-level features (such as a full 3D modeling of the head, geometric size and position of elements) and pixel-based, low-level features (such as a PCA-based metric for labeling the various feature bitmaps).
