摘要： A method of decoding viewport bitstreams includes decoding first video content; transmitting, information about (i) a speed of a user's head movement while viewing the first video content and (ii) an available bandwidth; receiving a streaming bitstream that includes (i) a first coded video bitstream having a segment size defined for a viewport based on the available bandwidth and a head speed threshold corresponding to the speed of the user's head movement such that the segment size is inversely proportional to the speed of the user's head movement, the first coded video bitstream having a first resolution, and (ii) a second coded video bitstream having a second resolution corresponding to a background having a constant segment duration or size, the second resolution being lower than the first resolution; and rendering second video content using the first coded video bitstream and the second coded video bitstream.

摘要： Methods and devices are provided for encoding, transmitting and decoding 3DoF+ volumetric video. At the encoding stage one input view (among all the input ones) is selected to convey the viewport dependent light effect and its id is transmitted to the decoder as an extra metadata. On the decoder side, when patches coming from this selected view are available for the rendering of the viewport, they are preferentially used regarding the other candidates whatever the view to synthesize position.

摘要： In one aspect, a device includes at least one processor and storage accessible to the at least one processor. The storage includes instructions executable by the at least one processor to track a location of at least a segment of a wire of a virtual reality (VR) headset. The instructions are also executable to, based on the location and responsive to a trigger, present a notification regarding the location on a display of the VR headset.

摘要： A virtual wave creation system comprises an eyewear device that includes a frame, a temple connected to a lateral side of the frame, and a depth-capturing camera. Execution of programming by a processor configures the virtual wave creation system to generate, for each of multiple initial depth images, a respective wave image by applying a transformation function that is responsive to a selected input parameter to the initial three-dimensional coordinates. The virtual wave creation system creates a warped wave video including a sequence of the generated warped wave images. The virtual wave creation system presents, via an image display, the warped wave video.

摘要： There is provided an image processing device that processes a projection image presented to a plurality of persons at the same time. The image processing device specifies an overlapping area in which fields of view of two or more users overlap based on information on each user, classifies objects included in the overlapping area into a first object group and a second object group, generates a common image common to all users, made up of the first object group, generates individual images different for each user, made up of the second object group, and determines an output protocol for displaying the individual images.

摘要： Systems and techniques for determining a list of geographic location candidates from an image of an environment are described. Open source data indicative of the earth's surface may be obtained and combined into grids to create region data to gain a representation of the earth's surface within each grid cell. An image of an environment may be obtained from an unknown camera. Image characteristics may be compared to the region data to determine error between the image characteristics and projections of the region data. A list of lowest error geographic location candidates may be determined and provided to the user.

摘要： Embodiments disclose a real-time surgery method and apparatus for displaying a stereoscopic augmented view of a patient from a static or dynamic viewpoint of the surgeon, which employs real-time three-dimensional surface reconstruction for preoperative and intraoperative image registration. Stereoscopic cameras provide real-time images of the scene including the patient. A stereoscopic video display is used by the surgeon, who sees a graphical representation of the preoperative or intraoperative images blended with the video images in a stereoscopic manner through a see-through display.

The user specifies areas of attention wherein said areas of attention or hotspots. Tracking movement of the hotspots generating a trajectory of said at least one object. Generating a cloud of points and tracking said points to detect configurations of points most similar to the initially defined hotspot. Obtaining a three dimensional topology defining a volume of interest in a three-dimensional space. Building virtual structures or pseudo objects that are placed within a spherical environment generated on the input video.

摘要： A device includes a processor that is configured to obtain first facets of a first wide field-of-view image. An object is identified in a facet of the first facets. A second wide field-of-view image is obtained. A location of the object is identified in the second wide field-of-view image. Using the location of the object, the second wide field-of-view image is partitioned into second facets such that no boundary of any of the second facets overlaps the object. The second facets are then encoded in a compressed bitstream.
