    摘要： A cache management operation. In one embodiment, a first recall value for a first unit of data is generated, a second recall value for a second unit of data is generated, and the first and second recall values are compared. The unit of data having the higher recall value is stored in a first section of a storage device. The unit of data having the lower recall value is stored in a second section of a storage device. A greater amount of compression is performed on the unit of data having the lower recall value.

    摘要： An apparatus and method for time synchronization of a plurality of multimedia streams are described. In one embodiment, the method includes the concurrent capture of multimedia data via a plurality of multimedia platforms. During the concurrent capture of the multimedia data, each of the multimedia platforms receives a synchronization signal from a synchronization generation unit. In response, each platform processes a received synchronization signal to generate a common reference clock signal among each of the platforms. Once the common clock signal is generated, each of the platforms synchronizes captured multimedia data to form multimedia stream data according to the common reference clock signal. As such, the plurality of multimedia platforms are able to perform collaborative signal processing tasks of multimedia streams, including, for example, array signal processing algorithms.

    摘要： A procedure for fast training and evaluation image classification systems using support vector machines (SVMs) with linear input features of high dimensionality is presented. The linear input features are derived from raw image data by means of a set of m linear functions defined on the k-dimensional raw input data, and are used for image classification, including facial recognition tasks.

    摘要： Systems and methods are provided through which a graphic image is classified in terms of being natural versus computer generated, or being a scientific slide presentation versus a comic image. The image is classified by extracting appropriate feature(s) from the image, and using the feature(s) to determine, within a predetermined degree of accuracy, the graphic classification of the image.The classification determination uses a trained model. The trained model is created by using machine learning algorithms such as Neural Networks, Support Vector Machines, and Learning Vector Quantizations.Subsequently, the trained model is used to classify a group of images of unknown classification automatically.

    摘要： A method, machine readable medium, and system are disclosed. In one embodiment the method comprises generating an acoustic signal from an actuator of a first computing device, receiving the acoustic signal with a sensor of a second computing device, receiving the acoustic signal with a sensor of a third computing device, generating an estimate of a difference between the amount of time required for the acoustic signal to travel from the actuator of the first computing device to the sensor of the second computing device and the amount of time required for the acoustic signal to travel from the actuator of the first computing device to the sensor of the third computing device, wherein the sensors and actuator are unsynchronized, and computing, based on the estimated difference in time, a physical location of at least one of the said sensors and actuator.
