MUCKE aims to mine a large volume of images, to structure them conceptually and to use this conceptual structuring in order to improve large-scale image retrieval. The last decade witnessed important progress concerning low-level image representations. However, there are a number problems which need to be solved in order to unleash the full potential of image mining in applications. The central problem with low-level representations is the mismatch between them and the human interpretation of image content. This problem can be instantiated, for instance, by the incapability of existing descriptors to capture spatial relationships between the concepts represented or by their incapability to convey an explanation of why two images are similar in a content-based image retrieval framework. We start by assessing existing local descriptors for image classification and by proposing to use co-occurrence matrices to better capture spatial relationships in images. The main focus in MUCKE is on cleaning large scale Web image corpora and on proposing image representations which are closer to the human interpretation of images. Consequently, we introduce methods which tackle these two problems and compare results to state of the art methods. Note: some aspects of this deliverable are withheld at this time as they are pending review. Please contact the authors for a preview.

Image Processing

The present invention provides an apparatus and method for encoding, storing, transmitting and decoding multimedia information in the form of scalable, streamed digital data. A base stream containing basic informational content and subsequent streams containing additive informational content are initially created from standard digital multimedia data by a transcoder. Client computers, each of which may have different configurations and capabilities are capable of accessing a stream server that contains the scalable streamed digital data. Each different client computer, therefore, may access different stream combinations according to a profile associated with each different client computer. Thus, the streams accessed from the server are tailored to match the profile of each client computer so that the best combination of streams can be provided to maximize the resolution of the 3D, audio and video components.

Method and apparatus that provides a scalable media delivery system

An electro-optic display, having at least one pixel capable of achieving any one of at least four different gray levels including two extreme optical states, is driven by displaying a first image on the display, and rewriting the display to display a second image thereon, wherein, during the rewriting of the display, any pixel which has undergone a number of transitions exceeding a predetermined value without touching an extreme optical state, is driven to at least one extreme optical state before driving that pixel to its final optical state in the second image.

Methods for driving electro-optic displays

Methods and apparatuses provide real-time or near real-time streaming of content, specified in one or more playlists, using transfer protocols such as an HTTP compliant protocol. In one embodiment, a method can execute a user application on a client device to present media files and to control presentation of the media files. The method can further run a media serving process on the client device to retrieve a playlist specifying the media files and a media source at which the media files are available, to retrieve the media files from the media source, and to decode the media files retrieved. The media serving process can call the user application to process a custom URL in order to obtain an object referred to by the custom URL.

Real-time or near real-time streaming

Techniques for transmitting graphical images in a network environment are described. According to the techniques, the amount of data of the graphical images that is transmitted is customized in accordance with client and/or server supplied information. The techniques enable graphical images to be transmitted more efficiently than previously possible, thus saving precious network bandwidth and reducing transmission time. The invention is particularly suitable for network (intranet or Internet) implementations wherein graphical images often need to be transferred.

Computer implemented method and system for transmitting graphical images from server to client at user selectable resolution

A method and apparatus for providing a flexible and scalable videoconferencing system for use in connection with a network provides for scalably encoding an image sequence for transmission onto the network. The encoding enables the encoded image sequence to be decoded at any one of at least two spatial resolutions and any one of at least two frame rates. The decoder, depending upon the computing platform, its resources, speed, and efficiencies, can select to decode the received image at any of the available spatial resolutions and at any of the available frame rates. A lower spatial resolution and/or a lower frame rate require less computing resources. Multiple received image sequences can be decoded simultaneously, at, for example, a lowest resolution. The decoded images can be displayed for viewing on the computer monitor at the desired spatial resolution level and frame rate.

Cipher block chaining decryption

In one embodiment, the present invention includes a multicore processor having a power controller with logic to dynamically switch a power management policy from a power biased policy to a performance biased policy when a utilization of the processor exceeds a threshold level. Thus at low utilizations, reduced power consumption can be realized, while at higher utilizations, greater performance can be realized. Other embodiments are described and claimed.

Dynamically modifying a power/performance tradeoff based on a processor utilization

In an embodiment, a processor comprises: a plurality of cores each to execute instructions; a plurality of thermal sensors, at least one of which is associated with each of the cores; and a power control unit (PCU) coupled to the cores. The PCU includes a thermal control logic to preemptively throttle a first core by a first throttle amount when a temperature of a second core exceeds at least one thermal threshold. Note that this first core may be preemptively throttled independently of a throttling of the second core and may have a temperature of the first core does not exceed any thermal threshold. Other embodiments are described and claimed.

Adaptive algorithm for thermal throttling of multi-core processors with non-homogeneous performance states

In one embodiment, the present invention includes a processor having a core and a power controller to control power management features of the processor. The power controller can receive an energy performance bias (EPB) value from the core and access a power-performance tuning table based on the value. Using information from the table, at least one setting of a power management feature can be updated. Other embodiments are described and claimed.
