Abstract: Techniques are shown for generating image frames from a media presentation. In one embodiment a computer implemented method is provided. The method includes identifying, by a processing device, image frames from a media presentation comprising a plurality of image frames. Candidate thumbnails are selected from the identified image frames. A probability is determined that a selected candidate thumbnail with a success ranking higher than other selected thumbnails is an optimum candidate thumbnail for representing the media presentation in view of a relationship between the success ranking of the selected candidate thumbnail and the success rankings of the other selected candidate thumbnails. Thereupon, data for displaying the selected candidate thumbnail to a user as a representative of the media presentation is provided by the processing device.

Abstract translation: 显示了从媒体演示中生成图像帧的技术。 在一个实施例中，提供了计算机实现的方法。 该方法包括由处理设备识别来自包括多个图像帧的媒体呈现的图像帧。 从识别的图像帧中选择候选缩略图。 考虑到所选候选缩略图的成功排名与另一选定缩略图的成功排名之间的关系，确定成功排名高于其他所选缩略图的选定候选缩略图是用于表示媒体呈现的最佳候选缩略图 候选人缩略图。 于是，由处理装置提供用于将用户显示所选候选缩略图作为媒体呈现的代表的数据。

Abstract: A method and apparatus for creating and updating a facial image database from a collection of digital images is disclosed. A set of detected faces from a digital image collection is stored in a facial image database, along with data pertaining to them. At least one facial recognition template for each face in the first set is computed, and the images in the set are grouped according to the facial recognition template into similarity groups. Another embodiment is a naming tool for assigning names to a plurality of faces detected in a digital image collection. A facial image database stores data pertaining to facial images detected in images of a digital image collection. In addition, the naming tool may include a graphical user interface, a face detection module that detects faces in images of the digital image collection and stores data pertaining to the detected faces in the facial image database, a face recognition module that computes at least one facial recognition template for each facial image in the facial image database, and a similarity grouping module that groups facial images in the facial image database according to the respective templates such that similar facial images belong to one similarity group.

Abstract translation: 公开了一种用于从数字图像的集合创建和更新面部图像数据库的方法和装置。 来自数字图像集合的一组检测到的面部与其相关的数据一起存储在面部图像数据库中。 计算第一组中每个面部的至少一个面部识别模板，并且将该组中的图像根据面部识别模板分组为相似组。 另一个实施例是用于将名称分配给在数字图像集合中检测到的多个面部的命名工具。 面部图像数据库存储与数字图像集合的图像中检测到的面部图像有关的数据。 此外，命名工具可以包括图形用户界面，面部检测模块，其检测数字图像集合的图像中的面部，并将与检测到的面部有关的数据存储在面部图像数据库中;面部识别模块，其计算至少一个 面部图像数据库中的每个面部图像的面部识别模板，以及相似性分组模块，其根据各个模板对面部图像数据库中的面部图像进行分组，使得相似的面部图像属于一个相似性组。
