Abstract: In some examples, an electronic device includes a machine learning circuit to detect a user break from an online meeting based on a video stream. In some examples, the machine learning circuit is to send an indicator in response to detecting the user break. In some examples, the electronic device includes a processor coupled to the machine learning circuit. In some examples, the processor is to replace a portion of the video stream with substitute video in response to the indicator.

Abstract: In some examples, an electronic device comprises an interface to receive a video of a human face, a memory storing executable code, and a processor coupled to the interface and to the memory. As a result of executing the executable code, the processor is to receive the video from the interface, use a facial detection technique to produce a sequence of images of the human face based on the video, use a neural network to predict a photoplethysmographic (PPG) signal based on the sequence of images, convert the PPG signal to a frequency domain signal, and determine a heart rate by performing a frequency analysis on the frequency domain signal.

Abstract: A machine learning model may be trained with virtual renderings of each three-dimensional (3D) model in a set of 3D models in different poses and with different backgrounds. The system may identify a 3D object in an image as corresponding to one of the 3D models. The system may estimate a pose of the 3D object identified in the image and generate a detection mask. The system may generate a model mask based on a rendering of the identified 3D model in the estimated pose. A defect visualization subsystem may render a scaled overlay image of the detection mask and the model mask. In some examples, the system may detect a defect based on a calculated difference between the detection mask the model mask.

Abstract: One example of a video monitoring system includes a frame acquisition subsystem, a stage gate motion detection subsystem, a person detection subsystem, a face recognition subsystem, and an alert emission subsystem. The frame acquisition subsystem extracts frames from an input video. The stage gate motion detection subsystem separates background motion from foreground motion within frames. The person detection subsystem detects people including faces and bodies within the foreground motion. The face recognition subsystem matches detected faces to previously registered users. The alert emission subsystem provides alerts based on events detected by the stage gate motion subsystem, the person detection subsystem, and the face recognition subsystem.

Abstract: In some examples, a non-transitory computer-readable medium stores executable code, which, when executed by a processor, causes the processor to receive a video of at least part of a human torso, use a neural network to produce multiple vector fields based on the video, the multiple vector fields representing movement of the human torso, and determine a respiration rate of the human torso using the multiple vector fields.

Abstract: An example system includes a first camera to capture a first image of a first facial body part and a second camera to capture a second image of a second facial body part. The example system further includes a transformation engine to transform respective scales of the first image and the second image to a scale of full facial images. The example system further includes a local location engine to: identify first facial landmarks and second facial landmarks in respective transformed versions of the first image and the second image, the first facial landmarks and the second facial landmarks used to determine that an action has occurred.

Abstract: In one example in accordance with the present disclosure, an electronic system is described. The electronic system includes a scanning device to capture an image of an object. The object includes encoded data formed therein. An attribute determiner of the electronic system determines an actual value of a surface attribute of the object. The electronic system includes an extraction device to extract from the image of the object, a target value for the surface attribute from the encoded data. A comparator of the electronic system determines if a difference between the actual value and the target value has a specified value.

Abstract: A query is submitted to a search engine, where the query includes an identification of a symbol. A bounding box is generated in an unlabeled image returned by the search engine in response to the query. A confidence score is also generated that indicates a likelihood of the symbol being present in a portion of the unlabeled image enclosed by the bounding box. The unlabeled image is selected as a training image for training a system to recognize the symbol, when the confidence score is above a predefined threshold.
