摘要： Identification of media content, such as audio, can be performed through use of watermarking or fingerprinting (aka content signature) technologies. Aspects of these technologies may be combined to advantageous effect. For example, in dealing with the problem of fingerprint errors arising from object distortion, operations known from digital watermarking systems can be employed.

摘要： Space-time solutions are determined by exchanging pings among nodes in a network. Each ping includes a current space-time state of the transmitting node, which includes the transmitting node's currently estimated location and corrected time (as a count stamp). A particular node in the network receives pings from the other nodes in the network and uses the data in the received pings to estimate its own current position and to correct its own free-running clock relative to a common system time. As a service to the network, the particular node then transmits its corrected time (as a count stamp) and estimated position to the other nodes. In some embodiments, the space-time solutions discussed herein are used as backup to other navigation systems, such as the Automatic Dependent Surveillance-Broadcast (ADS-B) system.
摘要翻译：通过在网络中的节点之间交换ping来确定时空解决方案。每个ping包括发送节点的当前时空状态，其包括发送节点的当前估计位置和校正时间（作为计数戳）。网络中的特定节点从网络中的其他节点接收ping，并使用接收到的ping中的数据来估计其自己的当前位置，并相对于公共系统时间修正自己的自由运行时钟。作为对网络的服务，特定节点然后将其校正时间（作为计数戳）和估计位置发送到其他节点。在一些实施例中，本文所讨论的时空解决方案被用作对诸如自动相关监视广播（ADS-B）系统的其它导航系统的备份。

摘要： A classification scheme assigns samples of the watermarked media to classes based on a classification criteria indicating a likely presence of a watermarked signal. Once classified, the scheme models a statistical distribution of the samples in each class. It then assigns a figure of merit to the samples in each class. A watermark detector and reader use the figure of merit to give greater weight to samples that are more likely to contain a watermark signal. Alternatively, the statistical distributions of the classes may be used to derive an estimate of a watermark signal in a pre-filtering stage of a watermark decoder. The watermark decoder then extracts a message from the estimate of the watermark signal.

摘要： Digital watermark embedding is incorporated into processes for generating halftone images. In a halftone process using a halftone screen, the halftone screen is used to determine the geometric distortion of an image. After determining the geometric distortion, a watermark decoder compensates for this distortion and retrieves an embedded digital watermark.

摘要： A method for assigning unique printer resolutions or signatures, i.e., a unique number of dots per inch, to a class, or models of printers or lines of postage meters. The number of dots per inch or resolution may be specified within a image on a document or within a postal indicia and later checked to determine if the image on document or the postal indicia has the correct resolution. The foregoing would be able to detect an image or postal indicia that was scanned into a computer and printed with a printer that did not have the number of dots per inch specified in the image or postal indicia.

摘要： Certain forms of distortion make it difficult to recover hidden data embedded in an audio or image signal by quanitzation techniques. To compensate for this distortion, an embedded data reader analyzes a statistical distribution (e.g., a histogram) of feature samples in an audio or image signal suspected of having hidden auxiliary data to derive an estimate of quantizers used to encode a reference signal. The estimated quantizers then recover the reference signal, and the reader uses the reference signal to determine and compensate for geometric or temporal distortion, like spatial scaling and rotation of image data, and time scale and speed changes of audio data. After compensating for such distortion, the reader can then more accurately recover hidden message data using quantization techniques to extract the message. The reference signal is preferably repeated in blocks of the image or audio data to enable synchronization at many points in an image or audio data stream.
摘要翻译：某些形式的失真使得难以通过Quanitzation技术恢复嵌入在音频或图像信号中的隐藏数据。为了补偿这种失真，嵌入式数据读取器分析疑似具有隐藏的辅助数据的音频或图像信号中的特征样本的统计分布（例如，直方图），以导出用于编码参考信号的量化器的估计。估计的量化器然后恢复参考信号，并且读取器使用参考信号来确定和补偿几何或时间失真，如图像数据的空间缩放和旋转以及音频数据的时间尺度和速度变化。在补偿这种失真之后，读者可以使用量化技术更准确地恢复隐藏的消息数据以提取消息。参考信号优选地以图像或音频数据的块重复，以实现图像或音频数据流中的许多点的同步。

摘要： A space time calibration method determines location and timing for nodes in a network using a model of the state of clocks in the network nodes and observations of clock count stamps over an observation interval. At least one of the nodes in the network is moving, and the nodes have free running clocks, with corresponding clock error parameters. The method obtains observations of clock stamps for transmissions between nodes occurring over a time interval. It applies the observations to a model of network state, and generates from the model an update of network state. This update is a function of the observations and an estimate of the network state. The network state provides estimates of location parameters and clock parameters of the nodes in the network.
