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: Examples include a system comprising a non-volatile memory to store a machine-learning data structure. Examples access the machine-learning data structure with a first processing resource, and examples access the machine-learning data structure with a second processing resource, which includes at least one graphics processing core, such that the machine-learning data structure is a shared memory space of the first processing resource and the second processing resource.

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: In an implementation, a non-transitory machine-readable storage medium stores instructions that when executed by a processor, cause the processor to allocate classifier data structures to persistent memory, read a number of categories from a set of training data, and populate the classifier data structures with training data including training-based, category and word probabilities calculated based on the training data.

Abstract: Recording and display of light fields is disclosed. An example apparatus includes a mapper to transform a first image into a second image based on a first map, a display device to output the second image as a first optical output, and a first optical member to pseudo-randomly distort at least a first portion of the first optical output to form a first light field.

Abstract: An example non-transitory computer-readable medium includes instructions. When executed by a processor, the instructions cause the processor to split a video frame into a first frame including blocks classified as natural and a second frame including blocks classified as artificial. The instructions also cause the processor to compress the first frame with a first compression technique. The instructions also cause the processor to compress the second frame with a second compression technique.

Abstract: Examples disclosed herein relate to updating memory management information to boot an electronic device from a reduced power mode. In one implementation, prior to entering a reduced power mode, an electronic device creates a snapshot of instructions in a logically volatile partition of a partitioned persistent memory and manage the snapshot as a logically persistent partition. Prior to entering a resume mode, the electronic device updates memory management information to remap a portion of the partitioned memory resource including the snapshot to be managed as a logically volatile partition. The electronic device may resume execution from the snapshot.
