摘要： A platform that is configured to be removably placed symmetrically on or about a user's head has at least a first transducer configured to capture vibration of the user's skull or facial movement generated by the user's voice activity and to detect the user's speaking activity. This first transducer converts the vibration or facial movement into a first electrical audio signal. The electrical audio signal from the first transducer is processed by circuitry or embodied software as voiced frames and/or as unvoiced frames, in which the voiced frames and/or the unvoiced frames are defined based at least on the first electrical audio signal. Multiple embodiments follow from this: where the first transducer is a vibration sensor; where voice is captured by an air microphone and filtering adaptation differs for the voiced versus unvoiced frames as defined by the first transducer, and another with at least three air microphones.

摘要： A method and system of identity masking to obscure identities corresponding to face regions in an image is disclosed. A face detector is applied to detect a set of possible face regions in the image. Then an identity masker is used to process the detected face regions by identity masking techniques in order to obscure identities corresponding to the regions. For example, a detected face region can be blurred as if it is in motion by a motion blur algorithm, such that the blurred region can not be recognized as the original identity. Or the detected face region can be replaced by a substitute facial image by a face replacement algorithm to obscure the corresponding identity.

摘要翻译：公开了一种识别掩蔽以掩盖对应于图像中的面部区域的身份的方法和系统。应用面部检测器来检测图像中的一组可能的面部区域。然后，使用身份掩码来通过身份掩蔽技术来处理检测到的面部区域，以便掩盖对应于该区域的身份。例如，检测到的脸部区域可以像通过运动模糊算法运动一样被模糊，使得模糊区域不能被识别为原始身份。或者通过面部替换算法可以通过替代面部图像来替换检测到的面部区域以遮蔽对应的身份。

摘要： A gradient-based silhouette projection method for rendering the surface of a 3-D object is described herein. A set of imaging points is selected for imaging the object. The object is imaged from each of the selected imaging points to generate a set of images and a set of binary silhouettes are extracted from the images of the object, with at least one silhouette per image. The binary silhouettes are each filtered to generate an equal number of gradient silhouettes. Each of the gradient silhouettes is projected to generate a set of gradient volume projections that are combined to yield a single combined gradient volume. A 3-D isosurface is generated from the combined gradient volume, with the 3-D isosurface thereby representing the 3-D object. In one example described herein, the binary silhouettes are filtered to generate gradient silhouettes by determining tubular neighborhoods for the binary silhouettes. The gradient volume projections are represented by voxels. The 3-D isosurface is determined from the combined gradient volume by applying a marching cubes algorithm to the voxels representing the combined gradient volume. A set of polygons representing the 3-D isosurface is generated by approximately determining the set of polygons representing the locus of all lines that do not intersect the 3D isosurface. The set of polygons is subsequently textured based upon texture information provided in the set of input images or from other sources. The various steps may be repeated while the object moves or otherwise changes. A technique employing only a single initial silhouette is also described. Apparatus embodiments are also described.
摘要翻译：本文描述了用于渲染3-D对象的表面的基于梯度的轮廓投影方法。选择一组成像点用于成像对象。从每个所选择的成像点成像对象以产生一组图像，并且从对象的图像中提取一组二进制轮廓，每个图像具有至少一个剪影。二进制轮廓都被过滤以产生相等数量的渐变剪影。每个渐变剪影被投影以产生一组梯度体积投影，其被组合以产生单个组合梯度体积。从组合的梯度体积产生3-D等值面，3-D等值面由此表示3-D物体。在本文描述的一个示例中，通过确定二进制轮廓的管状邻域来过滤二进制轮廓以生成渐变轮廓。梯度体积投影由体元表示。通过将表示组合梯度体积的体素应用行进立方体算法，从组合梯度体积确定3-D等值面。通过近似确定表示不与3D等值面相交的所有线的轨迹的多边形集合来生成表示3-D等值面的一组多边形。该组多边形随后根据在该组输入图像中提供的纹理信息或从其他来源进行纹理化。当对象移动或以其他方式改变时，可以重复各种步骤。还描述了仅使用单个初始轮廓的技术。还描述了装置实施例。

摘要： An animation system employs scattered data interpolation to provide fluent animation of still images. Discontinuities, such as cuts and holes, can be established within an image, to limit the range over which interpolation is carried out for a given deformation of a feature in the image, and thereby refine the control exerted by animated features. The amount of computational time and effort required to interpolate the change from one frame of an animation to the next is reduced by concentrating computation of the deformed image on areas of change. Computational requirements are further reduced by taking advantage of frame-to-frame coherence.
摘要翻译：动画系统采用分散数据插值来提供静态图像的流畅动画。可以在图像内建立诸如切口和孔的不连续性，以限制对于图像中的特征的给定变形进行内插的范围，从而改进由动画特征施加的控制。通过将变形图像的计算集中在变化的区域上，可以减少将动画内插到下一帧的变化所需的计算时间和精力。通过利用帧到帧的一致性进一步减少计算需求。
