摘要： The present invention is suitable for use in a communications system that downloads applications over a broadcast file system (BFS). An application services interface (ASI) provides the BFS an application file including a configuration file and an image file that are stored in a service manager in set-tops. Additionally, the ASI provides the BFS a content file that is included in the application file. The provided content file is separated into service files, where each service file is associated with a particular service. When a set-top requests a service, the associated service file is subsequently loaded onto the set-top. Alternatively, a service file is stored in memory until such time as another service is requested, which at that point the older service file is removed from memory to allow space for the newly requested service file.

摘要： Techniques are disclosed that involve face detection. For instance, face detection tasks may be decomposed into sets of one or more sub-tasks. In turn the sub-tasks of the sets may be allocated across multiple image frames. This allocation may be based on a multiple layer, quad-tree approach. In addition, face tracking tasks may be performed.

摘要： Detecting facial landmarks in a face detected in an image may be performed by first cropping a face rectangle region of the detected face in the image and generating an integral image based at least in part on the face rectangle region. Next, a cascade classifier may be executed for each facial landmark of the face rectangle region to produce one response image for each facial landmark based at least in part on the integral image. A plurality of Active Shape Model (ASM) initializations may be set up. ASM searching may be performed for each of the ASM initializations based at least in part on the response images, each ASM search resulting in a search result having a cost. Finally, a search result of the ASM searches having a lowest cost function may be selected, the selected search result indicating locations of the facial landmarks in the image.
摘要翻译：可以通过首先裁剪图像中检测到的面部的面部矩形区域并且至少部分地基于面部矩形区域来生成整体图像来检测在图像中检测到的面部中的面部界标。接下来，可以对面部矩形区域的每个面部标记执行级联分类器，以至少部分地基于积分图像来为每个面部标记产生一个响应图像。可以设置多个活动形状模型（ASM）初始化。可以至少部分地基于响应图像来对每个ASM初始化执行ASM搜索，每个ASM搜索导致搜索结果具有成本。最后，可以选择具有最低成本函数的ASM搜索的搜索结果，所选择的搜索结果指示图像中的面部地标的位置。

摘要： Avatars are animated using predetermined avatar images that are selected based on facial features of a user extracted from video of the user. A user's facial features are tracked in a live video, facial feature parameters are determined from the tracked features, and avatar images are selected based on the facial feature parameters. The selected images are then displayed are sent to another device for display. Selecting and displaying different avatar images as a user's facial movements change animates the avatar. An avatar image can be selected from a series of avatar images representing a particular facial movement, such as blinking. An avatar image can also be generated from multiple avatar feature images selected from multiple avatar feature image series associated with different regions of a user's face (eyes, mouth, nose, eyebrows), which allows different regions of the avatar to be animated independently.

摘要： According to one embodiment of the invention, a method includes generating a person-name Information Gain (IG)-Tree and a relation IG-Tree from annotated data. The method also includes tagging and partial parsing of an input document. The names of the persons are extracted within the input document using the person-name IG-tree. Additionally, names of organizations are extracted within the input document. The method also includes extracting entity names that are not names of persons and organizations within the input document. Further, the relations between the identified entity names are extracted using the relation-IG-tree.
