摘要: A watermark is embedded into audio/video/image/multimedia data using spread spectrum methodology. The watermark is extracted from watermarked data without the use of an original or unwatermarked version of the data by using spatial or temporal local averaging of the frequency coefficients of the watermarked data.

摘要: A pattern recognition method uses unsupervised metric learning starting from a mixture of normal densities which explains well observed data. An improved decision rule is provided for selecting the reference database element most likely to correspond to a query.
摘要翻译: 模式识别方法使用无监督的度量学习,从正常密度的混合开始,这解释了良好的观察数据。 提供改进的决策规则用于选择最可能对应于查询的参考数据库元素。

摘要: A technique for determining the ego-motion between two frames of an image that includes estimating likely values of the translation and rotation and making a five-dimensional search over the space of likely translations and rotations and finding the global minimum at the current motion estimate by a sum of squared differences cost function.

摘要: A stereoscopic computer vision system that uses a novel algorithm for obtaining the best match between corresponding features in the left and right images of desired objects in the image scene, finds the disparity between corresponding features in the left and right views and then uses the disparity to calculate the distance of the desired object from the two cameras used to provide the left and right images.

摘要: A teleconferencing video system uses two cameras at each station symmetrically positioned on opposite sides of the optical axis between the speaker and the monitor used to produce an image of the listener. The two cameras are used to provide from the two images observed by the cameras a virtual image corresponding to the image that would be viewed by a camera located on the first-mentioned optical axis. This system permits eye contact to be maintained between a speaker and a listener at different stations whereby the feeling of intimacy is enhanced.
摘要翻译: 电视会议视频系统在每个站处使用对称地位于扬声器和用于产生收听者的图像的监视器之间的光轴的相对侧上的两个摄像机。 这两个摄像机用于从摄像机观察到的两个图像提供与由位于第一个提到的光轴上的照相机观看的图像相对应的虚像。 该系统允许在不同站点的扬声器和收听者之间保持眼睛接触,从而增强亲密感。
