摘要： Sound representations and winner-take-all codes of auditory spectra are used in the identification of audio content. A transformation component converts a set of sound frames from audio content into a set of spectral slices. A spectral encoder component encodes the spectral slices of auditory spectra into winner-take-all codes with a winner-take-all hash function. An identification component identifies which spectral dimension of a subset of spectral dimensions within a spectral slice has highest spectral value according to the winner-take-all codes. Reference audio content is determined to be similar or matching to the audio content based on the winner-take-all codes.

摘要： Systems and methods for providing audio localization are provided. In some aspects, a method includes receiving phase offsets of a plurality of fixed transmitters from a source other than the plurality of fixed transmitters, detecting an audio localization signal from each of the plurality of fixed transmitters, determining a received phase of the audio localization signal from each of the plurality of fixed transmitters, determining time differences of flight from the mobile receiver to the plurality of fixed transmitters using the received phases, determining distance differences from the mobile receiver to the plurality of fixed transmitters using the time differences of flight, and determining the location of the mobile receiver by performing multilateration using the distance differences.

摘要： Systems and methods are provided herein relating to audio matching. Interest points that are onsets are generally very efficient in audio matching in that they are robust to multiple types of distortion. Prominent onsets can be detected within an audio signal excerpt as interest points and combined as a function of a set of interest points to form a descriptor. Descriptors associated with an audio signal excerpt that contain a set of prominent onsets as interest points can be used in matching the audio signal excerpt to an audio reference. The benefits in generating and using prominent onsets within descriptors improve the accuracy of an audio matching system.
摘要翻译：本文提供了与音频匹配有关的系统和方法。音频匹配中的兴趣点通常非常有效，因为它们对多种类型的失真具有鲁棒性。可以在音频信号摘录中检测突出的开始点作为兴趣点并且作为一组兴趣点的函数组合以形成描述符。与音频信号摘录相关联的描述符可以用于将音频信号摘录与音频参考相匹配。在描述符内生成和使用突出显示的优点可以提高音频匹配系统的准确性。

摘要： Methods and systems for generating high resolution composite imagery are provided. The methods and systems can create a fully-in-focus high resolution composite image by combining a number of source images in which only a part of the source image is in-focus. The composite image can be analyzed to identify portions of the composite image that satisfy an image quality metric. The capture of additional source images can be controlled based at least in part on the image analysis of the composite image. In addition, a control routine for capturing the plurality of source images can be dynamically adjusted based on the image quality of the individual source images.

摘要： The present invention includes a substantially modular pipeline multiplier for directly forming the correct final product of a 2's complement data word and a sign and magnitude coefficient word. In particular, the present invention includes circuitry for inserting logic 1 signals into the computations as sign extensions during multiplication whenever the data word is a negative 2's complement number.
