摘要： An object detection algorithm that generates a two-layer Gaussian Mixture Model (GMM) during a training session, and subsequent to the training session, uses the two-layer GMM to perform face detection. No labeling of local features is needed. The only input that is provided by a user is the setting of a few global parameters for the image being captured during the training session, such as, for example, the person's facial pose.
摘要翻译：在训练阶段和训练阶段之后生成双层高斯混合模型（GMM）的对象检测算法使用双层GMM进行人脸检测。不需要标记局部特征。由用户提供的唯一输入是在训练会话期间为例如人的面部姿势捕获的图像的几个全局参数的设置。

摘要： One provides (101) a media source bundle (200) as pertains to a given subject matter of interest to at least one end user. This media source bundle can comprise, for example and at least in part, content source locations for each of a plurality of independent content sources that each offer content regarding the given subject matter and wherein at least some of these independent content sources are associated with mutually non-compatible electronic content-delivery modalities. (In such an application, the media source bundle will be understood to not comprise the content itself.) These teachings will then provide for transmitting (102) a message that comprises, at least in part, this media source bundle to one or more corresponding end user recipient platforms (303).

摘要： Meta-data retrieved externally is determined to be relevant to the creation of an electronic programming guide (EPG) or relevant to a user's preferred programs. The meta-data is stored locally if it is determined that it is relevant to the creation of the EPG or if it is relevant to the user's preferred programs. All other meta-data is discarded. When a user requests meta-data, an attempt is made to retrieve the data from a local database, and if the attempt fails, then the meta-data is obtained from an external source.
摘要翻译：外部检索的元数据被确定为与创建电子节目指南（EPG）或与用户的首选节目有关的元数据相关。如果确定其与EPG的创建相关或者如果它与用户的优选程序相关，则元数据被存储在本地。所有其他元数据都被丢弃。当用户请求元数据时，尝试从本地数据库检索数据，如果尝试失败，则从外部源获得元数据。

摘要： At least one visual significance metric is determined (12) for at least some frames belonging to an original series of frames (11). Key frames are identified (13) as a function, at least in part, of the visual significance metric. Cumulative visual significance values are then determined (14) for at least some of the frames that intervene between each pair of key frames. These cumulative visual significance values are then used to identify (15) frames of additional content interest. Various frames are then selected (16) for use in a visual summary. In one embodiment, all of the key frames and frames of additional content interest are selected for inclusion in the visual summary.

摘要： A video encoding system (200) provides content adaptive rate control that includes a visual analyzer (208) utilizing at least one visual analysis tool for processing a video frame to provide visual information describing the video frame. An encoder (204) generates encoding status information relating to the video frame being processed. A rate controller (206) is responsive to the encoding status information generated by the encoder (204) and the visual information generated by the visual analyzer (208) to generate a rate control adjustment signal. The encoder (204) is responsive to the rate control adjustment signal for encoding the video frame.

摘要： A search system (200) for a database (224) including records having a multiple disparate types of media is provided. The search system supports queries, that include different types of search criteria, including content based retrieval search criteria. A fuzzy logic method (400) is provided for effectively combining the results of different types of search criteria. The fuzzy logic method also allows confidence levels entered by the user for search criteria to be considered in combining results. Retrieval relevance values for documents for at least some search criteria are used in the fuzzy logic method. For content based image retrieval searches, the retrieval relevance values are computed by mapping a distance between quantitative characterizations of a search basis image, and other images into a finite range.

摘要： An audio-visual content service provider processor (201) receives (101) audio-visual content (302) from at least a first content provider (203), which audio-visual content is to be distributed to end users (205) of the audio-visual content service provider processor. That audio-visual content service provider processor then facilitates distribution (102) of the audio-visual content to the end users (pursuant, for example, to a corresponding broadcast schedule (304)). This audio-visual content service provider processor also, however, locally records (104) the audio-visual content, in the absence of any corresponding specific requests from the end users, to thereby hold a recorded version of the audio-visual content for subsequent re-broadcasting to the end users.
