摘要:
A system and method for using images captured from a digital camera to control navigation through a three-dimensional user interface. The sequence of images may be examined to identify feature points to be tracked through successive frames of the images captured by the camera. A plurality of classifiers may be used to discern shift from rotation gestures, based on expected behavior of feature points in the image when the camera is shifted or rotated in position. The various classifiers may generate voting values for shift and rotation gestures, and the system can use historical gesture information to assist in categorizing a current gesture.

A method for providing face pose estimation for face detection may include utilizing a selected portion of classifiers in detectors to determine coarse pose information for a candidate face in an image, determining fine pose information for the candidate face based at least in part on the determined coarse pose information, and employing another portion of the classifiers in the detectors to perform face detection based at least in part on the fine pose information to determine whether the candidate face corresponds to a face. An apparatus and computer program product corresponding to the method are also provided.

A method for inputting characters to a mobile communication apparatus is disclosed. The method includes enabling input of strokes representing a first character in a first area of a touch sensitive display; determining the first character from the strokes; determining one or more candidates of characters for word association with the first character; presenting the one or more candidates on the display; and enabling selection among the one or more candidates. A mobile communication apparatus includes means for inputting characters is also disclosed.
摘要:
An electronic device having a memory, a display, control apparatus and a data processor. When the data processor executes a program stored in the memory of the electronic device, the electronic device receives an image containing a person, the image further containing a face component, the face component containing the face of the person; displays the image on the display; locates the face component within the image; emphasizes the face component; receives image annotation information concerning the face component; and saves the image annotation information to the memory of the electronic device. The image annotation information may take the form of contact information for use in a contact database. A method uses the face component to locate other images in the database that also contain the person, and adds the annotation information to those images.

Methods and apparatuses are provided for face detection. A method may include selecting a face detection parameter subset from a plurality of face detection parameter subsets. Each face detection parameter subset may include a subset of face posture models from a set of face posture models and a subset of image patch scales from a set of image patch scales. The method may further include using the selected face detection parameter subset for performing face detection in an image. Corresponding apparatuses are also provided.

An approach is provided for providing collaborative recognition using media segments. The recognition platform causes, at least in part, a generation of a request to determine recognition information for one or more media items associated with a device, one or more segments of the one or more media items, or a combination thereof. Next, the recognition platform determines to transmit the request to one or more other devices based, at least in part, on one or more device selection criteria. Then, the recognition platform receives the recognition information in response to the request. Further, the recognition platform processes and/or facilitates a processing of the recognition information to determine one or more identities of one or more users, one or more objects, or a combination thereof represented in the one or more media items.

A free hand gesture control user interface is described. Components of the interface system may include a stereo vision camera, or multiple cameras, a control unit, a projector and a projecting surface. In an automotive application, the projecting surface may be the windscreen in the vehicle or a mounted screen. The camera together with software modules in the control unit define a gesture acceptance border and a gesture acceptance space within which hand gestures may be imaged, defined for various control actions, and executed. The hand images are analyzed in slices of the gesture acceptance space to determine hand orientation (open or closed) and/or motion.
摘要:
Various methods for local binary pattern based facial feature localization. One example method includes determining an eye state classification of an input image. The example method may also include selecting a texture model for a global shape and an associated mean shape based on eye center positions and the eye state classification, and adjusting locations of feature points defined by the mean shape based on the texture model for the global shape and an associated global shape model. Similar and related example methods and example apparatuses are also provided.

Various methods for feature extraction using local primitive code are provided. One example method includes determining an origin block within an image, an arc, an arc orientation, and a distance between the origin block and the arc. In this regard, the origin block may include one or more pixels of the image. The example method also includes determining at least one arc block. In this regard, the arc block may be located on the arc and the arc may be located with respect to the origin block based on the arc orientation and the distance. Some or all of the at least one arc blocks may include one or more pixels of the image. The example method also includes determining at least one feature value based on attributes of the origin block and the at least one arc block. Similar and related example methods and example apparatuses are also provided.
