    • Spherical microphone arrays provide an ability to compute the acoustical intensity corresponding to different spatial directions in a given frame of audio data. These intensities may be exhibited as an image and these images are generated at a high frame rate to achieve a video image if the data capture and intensity computations can be performed sufficiently quickly, thereby creating a frame-rate audio camera. A description is provided herein regarding how such a camera is built and the processing done sufficiently quickly using graphics processors. The joint processing of and captured frame-rate audio and video images enables applications such as visual identification of noise sources, beamforming and noise-suppression in video conferenceing and others, by accounting for the spatial differences in the location of the audio and the video cameras. Based on the recognition that the spherical array can be viewed as a central projection camera, such joint analysis can be performed.
    • 球面麦克风阵列提供了在给定的音频数据帧中计算对应于不同空间方向的声学强度的能力。 这些强度可以作为图像显示,并且如果可以足够快地执行数据捕获和强度计算,从而创建帧率音频相机,则以高帧速率生成这些图像以实现视频图像。 本文提供了关于如何构建这种相机并且使用图形处理器来处理足够快速的处理的描述。 通过考虑音频和摄像机位置的空间差异,联合处理和捕获的帧率音频和视频图像可使诸如视频识别噪声源,视频会议等中的波束成形和噪声抑制等应用 。 基于将球形阵列视为中央投影摄像机的认识,可以进行这种联合分析。

    • A method for object detection from a visual image of a scene. The method includes: using a first order predicate logic formalism to specify a set of logical rules to encode contextual knowledge regarding the object to be detected; inserting the specified logical rules into a knowledge base; obtaining the visual image of the scene; applying specific object feature detectors to some or all pixels in the visual image of the scene to obtain responses at those locations; using the obtained responses to generate logical facts indicative of whether specific features or parts of the object are present or absent at that location in the visual image; inserting the generated logical facts into the knowledge base; and combining the logical facts with the set of logical rules to whether the object is present or absent at a particular location in the scene.
    • 一种用于从场景的视觉图像进行物体检测的方法。 该方法包括:使用一阶谓词逻辑形式来指定一组逻辑规则以对关于待检测对象的上下文知识进行编码; 将指定的逻辑规则插入到知识库中; 获取场景的视觉图像; 将特定对象特征检测器应用于场景的视觉图像中的一些或所有像素,以在那些位置处获得响应; 使用所获得的响应来生成指示所述对象的特定特征或部分是否存在于所述视觉图像中的所述位置处的逻辑事实; 将生成的逻辑事实插入到知识库中; 以及将所述逻辑事实与所述逻辑规则集合,以组合所述对象是否存在于场景中的特定位置处。

    • A method for compensating sliding temperature influences on workpieces during a dimensional measurement process. For this purpose, the workpiece temperature and the relative position of the workpiece in relation to the measuring apparatus are recorded at the start and at the end of the actual measurement. By use of the recorded values, the temperature of the workpiece can be calculated at each instant of the dimensional measurement and the relative position of the workpiece in relation to the measuring apparatus and therefore the corrected scanning point can thus be determined. Thus, in the dimensional measurement of workpieces, while taking into account the temperature influences, the temperature straight line in the time interval from the start of measurement to the end of measurement is divided by intermediate measurements into part intervals, within which interpolation can be carried out. For a further improvement of these values, the instants of coordinate measurement are made to coincide with the instants of temperature measurement.
    • 在尺寸测量过程中补偿滑动温度对工件的影响的方法。 为此,在实际测量的开始和结束时记录工件温度和工件相对于测量装置的相对位置。 通过使用记录值,可以在尺寸测量的每个瞬间和工件相对于测量装置的相对位置计算工件的温度,因此可以确定校正的扫描点。 因此,在工件的尺寸测量中,考虑到温度影响,从测量开始到测量结束的时间间隔中的温度直线被中间测量除以部分间隔,其中可以进行内插 出来 为了进一步改进这些值,使坐标测量的时刻与温度测量的时刻一致。
