A method for providing a relightable avatar of a subject to a virtual reality application is provided. The method includes retrieving multiple images including multiple views of a subject and generating an expression-dependent texture map and a view-dependent texture map for the subject, based on the images. The method also includes generating, based on the expression-dependent texture map and the view-dependent texture map, a view of the subject illuminated by a light source selected from an environment in an immersive reality application, and providing the view of the subject to an immersive reality application running in a client device. A non-transitory, computer-readable medium storing instructions and a system that executes the instructions to perform the above method are also provided.

Deep relightable appearance models for animatable face avatars

A method of forming a pixel-aligned volumetric avatar includes receiving multiple two-dimensional images having at least two or more fields of view of a subject. The method also includes extracting multiple image features from the two-dimensional images using a set of learnable weights, projecting the image features along a direction between a three-dimensional model of the subject and a selected observation point for a viewer, and providing, to the viewer, an image of the three-dimensional model of the subject. A system and a non-transitory, computer readable medium storing instructions to perform the above method, are also provided.

Pixel-aligned volumetric avatars

A device for providing a reverse pass-through view of a user of a headset display to an onlooker includes an eyepiece comprising an optical surface configured to provide an image to a user on a first side of the optical surface. The device also includes a first camera configured to collect an image of a portion of a face of the user reflected from the optical surface in a first field of view, a display adjacent to the optical surface and configured to project forward an image of the face of the user, and a screen configured to receive light from the display and provide the image of the face of the user to an onlooker.

Reverse pass-through glasses for augmented reality and virtual reality devices

A method for updating a gaze direction for a transmitter avatar in a receiver headset is provided. The method includes verifying, in a receiver device, that a visual tracking of a transmitter avatar is active in a transmitter device, and adjusting, in the receiver device, a gaze direction of the transmitter avatar to a fixation point. Adjusting the gaze direction of the transmitter avatar comprises estimating a coordinate of the fixation point in a receiver frame at a later time, and rotating, in the receiver device, two eyeballs of the transmitter avatar to a point in a direction of the fixation point. A headset, a memory in the headset storing instructions, and a processor configured to execute the instructions to perform the above method, are also provided.

Gaze adjusted avatars for immersive reality applications

A method for training a real-time, modeling for animating an avatar for a subject is provided. The method includes collecting multiple images of a subject. The method also includes selecting a plurality of vertex positions in a guide mesh, indicative of a volumetric primitive enveloping the subject, determining a geometric attribute for the volumetric primitive including a position, a rotation, and a scale factor of the volumetric primitive, determining a payload attribute for each of the volumetric primitive, the payload attribute including a color value and an opacity value for each voxel in a voxel grid defining the volumetric primitive, determining a loss factor for each point in the volumetric primitive based on the geometric attribute, the payload attribute and a ground truth value, and updating a three-dimensional model for the subject. A system and a non-transitory, computer-readable medium storing instructions to perform the above method are also provided.

Mixture of volumetric primitives for efficient neural rendering

In one embodiment, a system may access an input image of an object captured by cameras, and the input image depicts appearance information associated with an object. The system may generate a first mesh of the object based on features identified from the input image of the object. The system may generate, by processing the first mesh using a machine-learning model, a position map that defines a contour of the object. Each pixel in the position map corresponds to a three-dimensional coordinate. The system may further generate a second mesh based on the position map, wherein the second mesh has a higher resolution than the first mesh. The system may render an output image of the object based on the second mesh. The system disclosed in the present application can render a dense mesh which has a higher resolution to provide details which cannot be compensated by texture information.

Systems and methods for rendering avatar with high resolution geometry

The disclosed computer system may include an input module, an autoencoder, and a rendering module. The input module may receive geometry information and images of a subject. The geometry information may be indicative of variation in geometry of the subject over time. Each image may be associated with a respective viewpoint and may include a view-dependent texture map of the subject. The autoencoder may jointly encode texture information and the geometry information to provide a latent vector. The autoencoder may infer, using the latent vector, an inferred geometry and an inferred view-dependent texture of the subject for a predicted viewpoint. The rendering module may be configured to render a reconstructed image of the subject for the predicted viewpoint using the inferred geometry and the inferred view-dependent texture. Various other systems and methods are also disclosed.

Systems and methods for rendering avatars with deep appearance models

In one embodiment, a method includes accessing a number of pictures of an object, constructing a modeling volume for three-dimensional modeling of the object by processing the number of pictures using a machine-learning framework, where the modeling volume is associated with a number of color and opacity information that are associated with a number of regions in the modeling volume, and rendering an image of the object from a view-point using the modeling volume, where each pixel of the image is rendered by projecting a virtual ray from the view-point and through the modeling volume, determining one or more of the number of regions in the modeling volume intersected by the virtual ray, and determining a color and an opacity of the pixel based on an accumulation of the color and opacity information associated with the one or more of the number of regions intersected by the virtual ray.

Three-dimensional modeling volume for rendering images

In one embodiment, a system may capture one or more images of a user using one or more cameras, the one or more images depicting at least an eye and a face of the user. The system may determine a direction of a gaze of the user based on the eye depicted in the one or more images. The system may generate a facial mesh based on depth measurements of one or more features of the face depicted in the one or more images. The system may generate an eyeball texture for an eyeball mesh by processing the direction of the gaze and the facial mesh using a machine-learning model. The system may render an avatar of the user based on the eyeball mesh, the eyeball texture, the facial mesh, and a facial texture.

Explicit eye model for avatar

A toothbrush having a substantially vertical orientation while at rest on a supporting surface, including a body having one end provided with a tooth-brushing element and another opposite end, said body having at least a part configured so that when the toothbrush is inclined, even close to a horizontal position, the toothbrush automatically self erects to the substantially vertical orientation to prevent a contact of said tooth-brushing element with the supporting surface.

Toothbrush

A toothbrush has a body having one end provided with a toothbrushing element and another opposite end, the body also having at least a part formed so that when the toothbrush is inclined, even close to a horizontal position, it automatically turns back to a substantially vertical orientation to prevent a contact of the toothbrushing element with a supporting surface.
