Abstract: Movement of a user in a user space is mapped to a first portion of a command action stream sent to a telerobot in a telerobot space. An immersive feedback stream is provided by the telerobot to the user. Upon movement of user into or proximate to a margin of user space, the first portion of the command action stream may be suspended. The user may re-orient in the user space, and may then continue to move, with movement mapping re-engaged and resumption of transmission of a second portion of command action stream. In this way, user may control a telerobot via movement mapping, even though user space and telerobot space may not be the same size.

Abstract: 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.

Abstract: A video communication system that replaces actual live images of the participating users with animated avatars. A method may include initiating communication between a first user device and a remote user device; receiving selection of a new avatar to represent a user of the first user device; identifying a new avatar file for the new avatar in an avatar database associated with the first user device; determining that the new avatar file is not present in a remote avatar database associated with the remote user device; and transmitting the new avatar file to the remote avatar database in response to determining that the new avatar file is not present in the remote avatar database.

Abstract: Technologies for generating an avatar with a facial expression corresponding to a facial expression of a user include capturing a reference user image of the user on a computing device when the user is expressing a reference facial expression for registration. The computing device generates reference facial measurement data based on the captured reference user image and compares the reference facial measurement data with facial measurement data of a corresponding reference expression of the avatar to generate facial comparison data. After a user has been registered, the computing device captures a real-time facial expression of the user and generates real-time facial measurement data based on the captured real-time image. The computing device applies the facial comparison data to the real-time facial measurement data to generate modified expression data, which is used to generate an avatar with a facial expression corresponding with the facial expression of the user.

Abstract: A video communication system that replaces actual live images of the participating users with animated avatars. A method may include selecting an avatar, initiating communication, capturing an image, detecting a face in the image, determining facial characteristics from the face, including eye movement and eyelid movement of a user indicative of direction of user gaze and blinking, respectively, converting the facial features to avatar parameters, and transmitting at least one of the avatar selection or avatar parameters.

Abstract: 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.

Abstract: 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.

Abstract: The present disclosure relates to methods for cooperative control of microcystis aeruginosa by using chub, bighead, catfish and daphnia, and belongs to the technical field of water treatment. The microcystis aeruginosa in a water body is controlled using a food chain relationship; the chub, the bighead, the catfish and the daphnia can directly eat the microcystis aeruginosa in a filtering manner; and meanwhile, the chub, the bighead and the catfish also can intake the daphnia, so as to indirectly consume the microcystis aeruginosa in the water body, wherein the fishes, the daphnia and the microcystis aeruginosa form the food chain relationship; in addition, the microcystis aeruginosa at the upper, middle and lower layers and a microcystis aeruginosa hypopus at the bottom layer can be controlled by fully utilizing the vertical spatial distribution difference of the three fishes in the water body.

Abstract: Methods, apparatuses, and articles associated with facial tracking and recognition are disclosed. In embodiments, facial images may be detected in video or still images and tracked. After normalization of the facial images, feature data may be extracted from selected regions of the faces to compare to associated feature data in known faces. The selected regions may be determined using a boosting machine learning processes over a set of known images. After extraction, individual two-class comparisons may be performed between corresponding feature data from regions on the tested facial images and from the known facial image. The individual two-class classifications may then be combined to determine a similarity score for the tested face and the known face. If the similarity score exceeds a threshold, an identification of the known face may be output or otherwise used. Additionally, tracking with voting may be performed on faces detected in video.

Abstract: 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.
