摘要： A text-dependent speaker verification technique that uses a generic speaker-independent speech recognizer for robust speaker verification, and uses the acoustical model of a speaker-independent speech recognizer as a background model. Instead of using a likelihood ratio test (LRT) at the utterance level (e.g., the sentence level), which is typical of most speaker verification systems, the present text-dependent speaker verification technique uses weighted sum of likelihood ratios at the sub-unit level (word, tri-phone, or phone) as well as at the utterance level.
摘要翻译：一种文本相关的扬声器验证技术，其使用一般的与扬声器无关的语音识别器进行强大的扬声器验证，并使用与扬声器无关的语音识别器的声学模型作为背景模型。现在的文本相关说明者验证技术不是在大多数说话人验证系统的典型的话语级别（例如，句子级别）上使用似然比检验（LRT），而是使用子单元中的似然比加权和水平（单词，三话电话或电话）以及话语水平。

摘要： A search-centric hierarchical browser history technique that provides for the creation of a Web search history hierarchy organized according to the search queries that a user has conducted. In one embodiment, search queries occupy the highest level of the search history hierarchy and all Web sites/search results relating to a particular search query that the user accessed are hierarchically organized below that query. In another embodiment, queries may also be optionally grouped into a higher-level hierarchy that reflects search topics.

摘要： A graph layout technique that creates a layered graph layout with a given aspect ratio. The present layered graph layout technique better utilizes the available space and, at the same time, creates an aesthetically pleasing drawing of a directed graph. In one embodiment it determines the layout of the new graph based on a modified Sugiyama technique combined with a modified Coffman-Graham scheduling algorithm. Given a directed graph and a desired aspect ratio, it uses a binary search and the Coffman-Graham scheduling algorithm to find a layout of the graph that has an aspect ratio that matches the given aspect ratio of the available space.

摘要： An energy based technique to estimate the positions of people speaking from an ad hoc network of microphones. The present technique does not require accurate synchronization of the microphones. In addition, a technique to normalize the gains of the microphones based on people's speech is presented, which allows aggregation of various audio channels from the ad hoc microphone network into a single stream for audio conferencing. The technique is invariant of the speaker's volumes thus making the system easy to deploy in practice.

摘要： The perceptual scalable audio coding/decoding technique lies in the use of a psychoacoustic mask to guide residue coding in enhancement layer coders. At the encoder, a psychoacoustic mask is calculated for the enhancement layer coders or is simply extracted from the coded base layer bitstream. One can also decode the coded base layer bitstream into the audio waveform, and calculate the psychoacoustic mask from the decoded base layer waveform. Furthermore, a predictive technology can be used to refine the psychoacoustic mask derived from the base layer bitstream to form a more accurate psychoacoustic mask of the enhancement layer. In addition, one can calculate the enhancement layer psychoacoustic mask from the original audio, and send the difference between the enhancement layer psychoacoustic mask and the base layer psychoacoustic mask as side information to the decoder. This psychoacoustic mask may then be used for the perceptual coding and decoding of the residue.

摘要： A technique for image compositing which allows a user to select the best image of an object, such as for example a person, from a set of images interactively and see how it will be assembled into a final photomontage. A user can select a source image from the set of images as an initial composite image. A region, representing a set of pixels to be replaced, is chosen by the user in the composite image. A corresponding same region is reflected in one or more source images, one of which will be selected by the user for painting into the composite image. The technique optimizes the selection of pixels around the user-chosen region or regions for cut points that will be least likely to show seams where the source images are merged in the composite image.

摘要： A system and method for optimizing the performance of a graphics intensive software program for graphics acceleration hardware. This system and method encompasses a procedure that validates the different functions of a 3D acceleration capable video card, decides whether to use the acceleration hardware and optimizes the software application to selectively use the functions that work on the specific video acceleration card. Functions checked include sub-pixel positioning, opacity, color replacement and fog. If these tests are successful, then the graphics acceleration is used by the software application. However, if the tests are not successful the decision is made not to use graphics accelerator. Those with ordinary skill in the art will realize that it is not necessary to perform all of the tests in a specific order. Additionally, other types of tests could be performed to ensure software application and video card compatibility before the software application is uses graphics acceleration to render 3D graphics.

摘要： Embodiments consistent with the subject matter of this disclosure may transparently project text fragments from one or more buffers into one or more projection buffers by reference, instead of by copying. Clients or applications, such as, for example, compilers, language services, an editor's rendering system, or other client or application, may transparently process the projected text fragments projected into the projection buffers as if processing simple text files. In some embodiments, text of a first language, embedded in a document having text of one or more other languages, may be projected to a projection buffer and provided to an application, which may process text of the first language. In other embodiments, text may be elided from a document by projecting to a projection buffer only text not to be elided from the document.

摘要： A real-time low frame-rate video compression system and method that allows the user to perform face-to-face communication through an extremely low bandwidth network. The system and method employs image cropping and morphing to reduce frame rates. At the encoder side, the system is able to automatically select only a few good faces from the original sequence with high visual quality and compress and transmit them. At the decoder side, the system use image-morphing based rendering method to generate a normal frame-rate video. Experimental results show that the system is superior to more traditional video codecs for low bit-rate face-to-face communication.
