A high-definition image is preprocessed to generate a substantially losslessly-reconstructable set of image components that include a relatively low-resolution base image and a plurality of extra-data images that provide for progressively substantially losslessly reconstructing the high-definition image from the base image, wherein a single primary-color component of the extra-data images provides for relatively quickly reconstructing full-resolution intermediate images during the substantially lossless-reconstruction process.

Embodiments provide techniques for rendering augmented reality effects on an image of a user's face in real time. The method generally includes receiving an image of a face of a user. A global facial depth map and a luminance map are generated based on the captured image. The captured image is segmented into a plurality of segments. For each segment in the plurality of segments, a displacement energy of the respective segment is minimized using a least square minimization of a linear system for the respective segment. The displacement energy is generally defined by a relationship between a detailed depth map, the global facial depth map and the luminance map. The detailed depth map is generated based on the minimized displacement energy for each segment in the plurality of segments. One or more visual effects are rendered over the captured image using the generated detailed depth map.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for a multi-resolution image. The methods, systems, and apparatus include actions of obtaining an image, sectioning the image into unscaled sections and sections to downscale, generating downscaled sections from the sections to downscale, providing the unscaled sections and the downscaled sections to a server.

Methods, apparatus, systems and articles of manufacture are disclosed for super-resolution rendering. An example apparatus includes a data handler to generate a multi-sample control surface (MCS) frame based on a color frame, a feature extractor to obtain features from the color frame, a depth frame, and the MCS frame, a network controller to generate spatial data and temporal data based on the features, and a reconstructor to generate a high-resolution image based on the features, the spatial data, and the temporal data.

A control device includes a receiver, a generator, and a controller. The receiver receives a shared image to be shared with a user from a poster through a communication line. The generator generates a presented image, the presented image being an image that is to be presented to the user and that is obtained by processing the shared image such that the image is different from the shared image received by the receiver. The controller performs control to transmit the presented image to the poster through the communication line to notify the user of content of the shared image.

A 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transfer rate beyond a 4th generation (4G) communication system, such as a long term evolution (LTE) system and a method for supporting, by a first terminal, switching between a plurality of modes for a call is provided. The method includes performing a capability negotiation for a call with a second terminal, and establishing a first connection between the first terminal and a call server according to a first mode among the plurality of modes for the call with the second terminal after performing the capability negotiation, wherein the performing of the capability negotiation includes transmitting a first message including information indicating a media attribute of each of two or more modes of the plurality of modes to the call server.

An image rendering method, device, and system, a storage medium, and an image display method are provided. The image rendering method includes: acquiring an image to be displayed; according to a gaze point of human eyes on a display screen, obtaining a gaze point position on the image to be displayed; determining, according to the gaze point position, a first sampling area and a second sampling area of the image to be displayed; performing first resolution sampling on the first sampling area to obtain a first display area; performing second resolution sampling on the image to be displayed to obtain a second display area corresponding to the second sampling area, a resolution of the second sampling area being greater than that of the second display area; and splicing the first display area and the second display area to obtain an output image to be transmitted to the virtual reality device.

An electronic device includes a processor that is configured to, based on receiving a first partial image from among a plurality of partial images obtained by an input device by dividing an image, obtain first image quality information based on the first partial image and transmit the first image quality information to an external electronic device, based on receiving, from the external electronic device, second image quality information obtained from a second partial image among the plurality of the partial images, obtain image quality processing information corresponding to the image based on the first image quality information and the second image quality information, and process the first partial image based on the image quality processing information, and transmit, via the communication interface, the first partial image processed to one of a plurality of display modules included in an external display device.

Rotation between landscape and portrait modes or vice versa may be supported in wireless display interfaces coupled to a platform by having the platform sense rotation change in the platform or in the display. This enables counter rotation of the frame buffer or rotated rendering of the content to ensure that content is presented upright to the end user.

Systems and methods for screen sharing are provided. The screen sharing may comprise providing image data from a sender system to a receiver system. The receiver system may be a Virtual Reality [VR] system configured to render the image data in a virtual environment by projecting the image data onto a virtual canvas. At the sender system, visual content may be identified to share with the receiver system. The rendering or display of the virtual environment by the receiver may impose legibility constraints on the visual content. An adjusted version of the visual content may be generated which provides improved legibility when viewed in the virtual environment. The image data representing the adjusted version may then be provided to the receiver system. Accordingly, the legibility of the visual content shared by the sender system may be improved when rendered, displayed and subsequently viewed by a user in the virtual environment.
