    • A facial feature extraction method and apparatus uses the variation in light intensity (gray-scale) of a frontal view of a speaker's face. The sequence of video images are sampled and quantized into a regular array of 150.times.150 pixels that naturally form a coordinate system of scan lines and pixel position along a scan line. Left and right eye areas and a mouth are located by thresholding the pixel gray-scale and finding the centroids of the three areas. The line segment joining the eye area centroids is bisected at right angle to form an axis of symmetry. A straight line through the centroid of the mouth area that is at right angle to the axis of symmetry constitutes the mouth line. Pixels along the mouth line and the axis of symmetry in the vicinity of the mouth area form a horizontal and vertical gray-scale profile, respectively. The profiles could be used as feature vectors but it is more efficient to select peaks and valleys (maximas and minimas) of the profile that correspond to the important physiological speech features such as lower and upper lip, mouth corner, and mouth area positions and pixel values and their time derivatives as visual vector components. Time derivatives are estimated by pixel position and value changes between video image frames. A speech recognition system uses the visual feature vector in combination with a concomitant acoustic vector as inputs to a time-delay neural network.
    • 面部特征提取方法和装置使用说话者脸部正视图的光强度(灰度)的变化。 视频图像的序列被采样和量化为150×150像素的规则阵列,其自然地沿着扫描线形成扫描线和像素位置的坐标系。 通过对像素灰度进行阈值定位并找到三个区域的质心来定位左眼区域和右眼区域。 连接眼睛区域重心的线段以直角平分,形成对称轴。 通过与对称轴成直角的口区域的质心的直线构成口线。 沿嘴口的像素和口区附近的对称轴分别形成水平和垂直的灰度轮廓。 轮廓可以用作特征向量,但是更有效地选择对应于重要的生理语音特征(例如下唇和上唇,嘴角和嘴区域位置和像素)的轮廓的峰和谷(最大值和最小值) 值和它们的时间导数作为视觉矢量分量。 时间导数由视频图像帧之间的像素位置和值变化来估计。 语音识别系统使用视觉特征向量与伴随的声矢量相结合,作为时间延迟神经网络的输入。

    • According to the present invention, an internet target marketing system, method and computer program for distributing online advertising to viewers based upon the viewers' interests is provided. Specific embodiments according to the present invention can use an n-way matching of user's concepts of interest, advertiser's concepts and a currently viewed document to target advertising to the view of the current document. Some embodiments can generate a contextually sensitive advertisement for each page viewed in a browser, thereby associating an advertisement with every page in a document. Specific embodiments can associate advertising with documents that are substantially free of embedded advertisements, for example. Alternative embodiments can include embedded advertising, however.

    • A method and apparatus to precisely track the position of the writing instrument, specifically the writing end, such as the tip, of a pen. One embodiment of the invention described herein includes a writing instrument containing acceleration sensors and angular velocity sensors. Data from these sensors are processed via an Euler transform to determine the strokes made with the writing instrument. Corrections may be made to improve upon the output of the Euler transform. The data describing the strokes may include graphical representations of the strokes actually made with the writing instrument. Data describing the strokes may be stored or processed to accomplish a variety of tasks such as recording information, faxing a message, recording an appointment, or other such tasks.
