Abstract: Approaches to enable a computing device, such as a phone or tablet computer, to utilize a number of cues to detect the presence of a face (or head) in an image captured by a camera of the computing device. The cues may include the elliptical shape of the face, the stereo disparity signature of the face, color or image brightness, among others. The facial detection may be performed by using a boosted classifier ensemble that has been trained using a plurality of images that are known (i.e., have been previously identified) to contain faces. The classifier ensemble can combine a number of different cues, such as the elliptical shape and/or stereo disparity signature, to be used for detecting faces within an image.

Abstract: A processing device receives, from a user device, image information associated with an image, the image information providing an indication of an application installed on the user device or a second electronic device. The processing device determines a descriptor associated with the application based on analyzing the image information. The processing device compares the descriptor to one or more stored image descriptors associated with each of a plurality of known applications. Based at least in part on the comparing, the processing device determines identifying information associated with the application. The processing device sends the identifying information to the user device.

Abstract: Systems and approaches provide for user interfaces (UIs) that are based on object tracking. For example, the object may be a user's head or face. As the user moves his head or face and/or tilts a computing device, the content displayed on the computing device will adapt to the user's perspective. The content may include three-dimensional (3D) graphical elements projected onto a two-dimensional (2D) plane and/or the graphical elements can be associated with textural shading, shadowing, or reflections that change according to user or device motion to give the user the impression that the user is interacting with the graphical elements in 3D environment. To enhance the user experience, a state of motion of the device can be determined and jitter and/or latency corresponding to the rendering of content can be altered so as to minimize or decrease jitter when the device is stationary and/or to decrease or minimize latency when the device is in motion.
