Abstract: In some examples, a controller can include a processing resource and a memory resource storing instructions to cause the processing resource perform object detection on a frame of a plurality of frames of a video signal, generate a bounding box around an object in the frame in response to the object detection detecting the object in the frame, perform a backlight adjustment of the frame, and generate an output frame having adjusted pixel values for each pixel from the backlight adjustment.

Abstract: Examples of methods for image enhancement are described. In some examples, a method includes segmenting an image into an object region and a background region. In some examples, the image has a first resolution. In some examples, the method includes generating, using a first machine learning model, an enhanced object region with a second resolution that is greater than the first resolution. In some examples, the first machine learning model has been trained based on object landmarks. In some examples, the method includes generating, using a second machine learning model, an enhanced background region with a third resolution that is greater than the first resolution. In some examples, the method includes combining the enhanced object region and the enhanced background region to produce an enhanced image.

Abstract: In an example implementation according to aspects of the present disclosure, a device, method, and storage medium. The device comprises a processor and memory with instructions to receive a digital image and extract administrative and descriptive metadata. The device stores the administrative and descriptive metadata in a knowledge base and determines a digital image quality score. The device creates a recommendation based on the administrative and descriptive metadata and the digital image quality score.

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: A pose estimation system may be embodied as hardware, firmware, software, or combinations thereof to receive an image of an object. The system may determine a first pose estimate of the object via a multi-view matching neural network and then determine a final pose estimate of the object via analysis by an iteratively-refining single-view matching neural network.

Abstract: An example of an apparatus is provided. The apparatus includes a preprocessing engine to preprocess an image of a print into a reduced format wherein the reduced format includes a plurality of pixels. The apparatus further includes a segmentation analysis engine to generate a plurality of labels. Each label of the plurality of labels is associated with a pixel of the plurality of pixels. The plurality of labels identifies each pixel of the plurality of pixels as a defective pixel or a non-defective pixel. The apparatus also includes a rendering engine to display defects in the reduced format based on the plurality of labels.

Abstract: In example implementations, a method is provided. The method may be executed by a processor. The method includes receiving an image. The image is analyzed to obtain facial features. Contextual information is obtained and a vector including a facial feature class of the facial features and contextual feature classes of the contextual information is generated. A facial recognition is then performed based on the vector.

Abstract: In some examples, a non-transitory machine-readable medium stores machine-readable instructions which, when executed by a processor of an electronic device, cause the processor to detect, by multiple image sensors, a user presence, to determine, responsive to the detection of the user presence, eye gaze angles of a user in relation to optical axes of the multiple image sensors, to identify a smallest eye gaze angle among the eye gaze angles, and to cause an image sensor of the multiple image sensors that has the smallest eye gaze angle to be an active image sensor of the electronic device.

Abstract: An example system includes a landmark engine to detect a facial landmark in an image of a face. The system includes a comparison engine to determine a difference between the facial landmark in the image and a facial landmark of a neutral face. The system also includes an action engine to determine whether a facial action unit occurred based on whether the difference satisfies a condition.
