Abstract: An augmented reality (AR) device, such as AR glasses, may include a microphone array. The sensitivity of the microphone array can be directed to a target by beamforming, which includes combining the audio of each microphone of the array in a particular way based on a location of the target. The present disclosure describes systems and methods to determine the location of the target based on a gaze of a user and beamform the audio accordingly. This eye-tracked beamforming (i.e., foveated beamforming) can be used by AR applications to enhance sounds from a gaze direction and to suppress sounds from other directions. Additionally, the gaze information can be used to help visualize the results of an AR application, such as speech-to-text.

Abstract: A technique is described for extracting or constructing a three-dimensional (3D) model from multiple two-dimensional (2D) images. In an embodiment, a foreground segmentation mask or depth field may be provided as an additional supervision input with each 2D image.

Abstract: Automatic detection of mechanical defects in piece parts, such as floor covering planks, enables removal of the defective parts off an inspection path. A bypass conveyor system enables defective parts to be transported beyond or around a manual inspection, enabling personnel performing the subsequent inspection to focus on appearance defects. Once the remaining parts have been inspected by a manual process, the parts transported by the bypass conveyor system are returned to the production line. Defective parts may be distinguished by a marking capability that provides the ability to mark according to a variety of classes of defects.
