Abstract: A system and method implement deep learning on a mobile device to provide a convolutional neural network (CNN) for real time processing of video, for example, to color hair. Images are processed using the CNN to define a respective hair matte of hair pixels. The respective object mattes may be used to determine which pixels to adjust when adjusting pixel values such as to change color, lighting, texture, etc. The CNN may comprise a (pre-trained) network for image classification adapted to produce the segmentation mask. The CNN may be trained for image segmentation (e.g. using coarse segmentation data) to minimize a mask-image gradient consistency loss. The CNN may further use skip connections between corresponding layers of an encoder stage and a decoder stage where shallower layers in the encoder, which contain high-res but weak features are combined with low resolution but powerful features from deeper decoder layers.

Control circuitry may estimate a brightness adaptation state of a user that is wearing the electronic device. The control circuitry may select a tone mapping curve and brightness level for the virtual reality content based on the user's adaptation state.

The control circuitry may optimize the brightness of the display based on the user's current adaptation state, or the control circuitry may shift the brightness of the display away from the user's adaptation level to help guide the adaptation state to the desired level.

Abstract: An augmented reality display system can include a partially transparent eyepiece, an ambient light sensor, and an image input device. The image input device can include a light source and a spatial light modulator. The system can also include a controller that determines that no virtual content is being displayed to the user and compares the ambient light to display light to determine if a light source shutoff criterion is satisfied. The light source shutoff criterion can be indicative of whether shutting off the light source that illuminates the spatial light modulator will result in a change in the display light that will be user-perceptible. If the light source shutoff criterion is satisfied, the controller can turn off the light source.

Abstract: A luminescence shock avoidance algorithm selectively limits the brightness level of a display device when the display device is activated in a dark environment to prevent the temporary vision impairment that can occur when a display device is activated in a dark environment. The algorithm receives the state of the display (e.g. on or in standby mode), and can optionally receive an ambient lighting value from an ambient light sensor and a user-selectable manual brightness adjustment setting to determine whether luminescence shock avoidance should even be triggered, and if it is triggered, how much should the brightness level of the display be limited.

Abstract: Images of various views of objects can be captured. An object mesh structure can be created based at least in part on the object images. The object mesh structure represents the three-dimensional shape of the object and includes a mesh with mesh elements. The mesh elements are assigned views first from a subset of views to texture large contiguous portions of the object from relatively few views. Portions that are not textured from the subset views are textured using the full set of views, such that all mesh elements are assigned views. The views first assigned from the subset of views and the views then assigned from the full plurality of views can be packaged into a texture atlas. These texture atlas views can be packaged with mapping data to map the texture atlas views to their corresponding mesh elements. The texture atlas and the object mesh structure can be sent to a client device to render a representation of the object.

Abstract: A sample mask is used to control which samples are used in a filtering operation such as bilinear filtering. A conventional filtering operation reads a set of samples based on a single coordinate and combines the samples to produce a filtered sample value. Such filtering operations are performed conventionally using fixed function units designed specifically to perform such filtering operations. However, for some applications, excluding one or more of the samples in producing a filtered sample value is desirable. In other applications, combining the samples using different weighting factors is also desirable. Techniques are disclosed herein for extending the capabilities of existing filtering units, for example, to exclude one or more samples in the filtering operation and for specifying different weighting rules for combining the samples.
