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 provided for detection of humans in images that include depth information. A methodology embodying the techniques includes segmenting an image into multiple windows and estimating the distance to a subject in each window based on depth pixel values in that window, and filtering to reject windows with sizes that are outside of a desired window size range. The desired window size range is based on the estimated subject distance and the focal length of the depth camera that produced the image. The method further includes generating classifier features for each remaining windows (post-filtering) for use by a cascade classifier. The cascade classifier creates candidate windows for further consideration based on a preliminary detection of a human in any of the remaining windows. The method further includes merging neighboring candidate windows and executing a linear classifier on the merged candidate windows to verify the detection of a human.

Abstract: Techniques are provided for estimation of human orientation and facial pose, in images that include depth information. A methodology embodying the techniques includes detecting a human in an image generated by a depth camera and estimating an orientation category associated with the detected human. The estimation is based on application of a random forest classifier, with leaf node template matching, to the image. The orientation category defines a range of angular offsets relative to an angle corresponding to the human facing the depth camera. The method also includes performing a three dimensional (3D) facial pose estimation of the detected human, based on detected facial landmarks, in response to a determination that the estimated orientation category includes the angle corresponding to the human facing the depth camera.

Abstract: The present disclosure is directed to face detection window refinement using depth. Existing face detection systems may perform face detection by analyzing portions of visual data such as an image, video, etc. identified by sub-windows. These sub-windows are now determined only based on pixels, and thus may number in the millions. Consistent with the present disclosure, at least depth data may be utilized to refine the size and appropriateness of sub-windows that identify portions of the visual data to analyze during face detection, which may substantially reduce the number of sub-windows to be analyzed, the total data processing burden, etc. For example, at least one device may comprise user interface circuitry including capture circuitry to capture both visual data and depth data. Face detection circuitry in the at least one device may refine face detection by determining criteria for configuring the sub-windows that will be used in face detection.

Abstract: Technologies for distributed generation of an avatar with a facial expression corresponding to a facial expression of a user include capturing real-time video of a user of a local computing device. The computing device extracts facial parameters of the user's facial expression using the captured video and transmits the extracted facial parameters to a server. The server generates an avatar video of an avatar having a facial expression corresponding to the user's facial expression as a function of the extracted facial parameters and transmits the avatar video to a remote computing device.

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.
