Abstract: The accuracy of object tracking using relatively low power gesture cameras can be improved by adjusting camera settings to ensure a sufficient level of contrast or texture to enable stereo disparity calculations for the representations of the object in the captured images. For general gesture input, for example, a user might use a variety of objects in various orientations, such that conventional face or object recognition processes may not be sufficient. Further, such processes are very resource intensive. By adjusting the camera settings (e.g., exposure, gain, and/or aperture) to ensure an adequate level of contrast, objects of an appropriate size and location can be tracked for purposes such as gesture input. Once such an object is identified, coordinates for a bounding box or other indicator can be transferred to any camera or sensor to be used for the tracking.
Abstract translation: 通过调整相机设置以确保足够的对比度或纹理水平，以便对拍摄图像中的对象的表示进行立体视差计算，可以提高使用相对低功率手势相机的对象跟踪的精度。 对于一般手势输入，例如，用户可以使用各种方向的各种对象，使得传统的面部或对象识别过程可能不足够。 此外，这样的过程是非常耗资源的。 通过调整相机设置（例如，曝光，增益和/或光圈）以确保足够的对比度，可以跟踪诸如手势输入之类的适当尺寸和位置的对象。 一旦识别出这样的物体，边界框或其他指示器的坐标可以传送到任何用于跟踪的相机或传感器。

Abstract: Various embodiments utilize two-dimensional (“2D”) and three-dimensional (“3D”) object features for purposes such as object recognition and/or image matching. For example, a user can capture an image (e.g., still images or video) of an object and can receive information about items that are determined to match the object. For example, the image can be analyzed to detect visual features (e.g., corners, edges, etc.) of the object and the detected visual features can be combined to generate a combined visual feature vector which can be used for object recognition, image matching, or other such purposes. Other approaches utilize the image to generate a 3D model of the object represented in the image, which can be used to determine at least one object or types of objects that match the object represented in the image.

Abstract: Systems and approaches are provided for robustly determining the motion of a computing device. Multiple cameras on the device can each capture a sequence of images, and the images can be analyzed to determine motion of the device with respect to a user, an object, or scenery captured in the images. The estimated motion may be complemented with measurements from an inertial sensor such as a gyroscope or an accelerometer to provide more accurate estimations of device motion than can be provided by image data or inertial sensor data alone. A computing device can then be configured to detect device motion as user input such as to navigate a user interface or to remotely control movement of another electronic device.

Abstract: An electronic device can have two or more pairs of cameras capable of performing three-dimensional imaging. In order to provide accurate disparity information, these cameras should be sufficiently rectified. Automatic rectification can be performed by periodically capturing images with the cameras of interest, and locating matching feature points in corresponding images captured by those cameras. Small misalignment errors can be treated as linear translations, such that a set of linear equations can be used to solve for the misalignments. Another process can process a set of homographies for the cameras until a cost function converges. Various other approaches can be used as well, such as to directly solve for yaw, pitch, and roll errors. Once this information is obtained, the misalignment values (or related values) can be stored for use in correcting images subsequently captured by those cameras.

Abstract: Systems and approaches are provided for tracking an object of interest using depth or disparity information, such as obtained by calculating stereo disparity between a pair of images. The depth or disparity information can be used as an additional signature for a template of the object of interest for tracking the object. A template that includes depth, distance, or disparity information for an object of interest may be invariant to the effects of lighting, such as shadows and changes in illumination conditions. Depth, distance, or disparity information can also provide information regarding shape and size that can be used to differentiate foreground objects. Depth, distance, or disparity information can also better handle occlusion. Depth, distance, or disparity information can also provide an additional disambiguating dimension for tracking an object.

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.
