Abstract: In example implementations, a method is provided. The method may be executed by a processor. The method includes receiving a reflected image of a mirrored display. At least one optimal display region is identified in the mirrored display around a main subject in the reflected image based on additional reflected subjects in the reflected image. A content is analyzed to determine an arrangement of the content in the at least one optimal display region. The content that is displayed is arranged in the at least one optimal display region.

Abstract: An audio signal classifier including a feature extractor to extract metadata from an audio signal, the metadata defining a plurality of features of the audio signal, the feature extractor to generate a feature vector including selected features of the audio signal, the selected features including a duration of the audio signal, and each selected feature having a feature value. A machine learning model trained to classify the audio signal as one of a plurality of audio signal classes based on the feature vector. The machine learning model to provide a plurality of class values based on the feature values, each class value corresponding to one of the plurality of audio signal classes, the plurality of class values together indicating the class of the audio signal.

Abstract: Acoustic echo cancellation for a video conference system is described. A location of a person in a room can be determined. An audio signal received from the location of the person can be captured using beamforming. An acoustic echo cancellation parameter can be determined based in part on the audio signal captured from the location of the person. Acoustic echo cancellation can be performed on the audio signal using the acoustic echo cancellation parameter.

Abstract: Examples of machine learning model training are described herein. In some examples, a method may include training, on an apparatus, an encoder machine learning model or a context machine learning model. In some examples, the method may include training the encoder machine learning model or the context machine learning model using negative samples in a latent space from emote devices and a ground truth.

Abstract: An example device includes a main display panel that includes a main array of pixels and an opening within the main array of pixels. The example device further includes a beam splitter positioned to communicate light through the opening within the main array of pixels, a sensor positioned with respect to the beam splitter to capture light incident on the opening within the main array of pixels, and a subarray including a pixel. The subarray is positioned with respect to the beam splitter to output light through the opening within the main array of pixels.

Abstract: An apparatus includes a support, a first camera, and second camera, and a processor. The support is configured to be mounted to a head of a user. The first camera is mounted on the support and positioned to capture a first image of a face of the user. The second camera is mounted on the support and positioned to capture a second image of the face of the user that is non-overlapping with the first image. The processor is mounted to the support and programmed to stitch the first image and the second image together to construct an image of the face of the user.

Abstract: In an example, an augmented reality display system includes a reflective surface, a depth scanner and processing apparatus comprising an image processor and an image generation engine. The depth scanner may be to scan the reflective surface and a subject via the reflective surface to acquire depth data. The image processor may be to determine, based on the depth data, a viewpoint for an augmentation of a reflected image. The image generation engine may be to generate the augmentation for display on the reflective surface.

Abstract: According to examples, an apparatus may include a processor and a memory on which is stored machine readable instructions that are to cause the processor to determine a reference frame from a plurality of frames received at multiple different times, in which each of the plurality of frames includes audio signal data, and in which the reference frame includes audio signal data that identifies a highest audio signal level among audio signals identified in the plurality of frames. The reference frame may be time-aligned with each of the plurality of frames other than the reference frame to obtain respective time-aligned frames. The audio signals identified in each of the respective time-aligned frames may be added together to generate respective added audio signals. The respective added audio signals may be combined together to obtain a combined audio signal and the combined audio signal may be outputted.

Abstract: Examples for global motion suppression in an event-driven camera are described herein. In some examples, global motion of an event-driven camera is detected based on a plurality of pixels of an event-driven image sensor detecting events. The global motion may be suppressed by event-driven image sensor circuitry in response to detecting the global motion.
