Abstract: Examples are described for overlaying primitives, arranged as concentric circles, in circular images onto respective mesh models to generate rectangular images representative of a 360-degree video or image. Portions of the rectangular images are blended to generate a stitched rectangular image, and image content for display is generated based on the stitched rectangular image.

Abstract: Techniques are described for generating and rendering video content based on area of interest (also referred to as foveated rendering) to allow 360 video or virtual reality to be rendered with relatively high pixel resolution even on hardware not specifically designed to render at such high pixel resolution. Processing circuitry may be configured to keep the pixel resolution within a first portion of an image of one view at the relatively high pixel resolution, but reduce the pixel resolution through the remaining portions of the image of the view based on an eccentricity map and/or user eye placement. A device may receive the images of these views and process the images to generate viewable content (e.g., perform stereoscopic rendering or interpolation between views). Processing circuitry may also make use of future frames within a video stream and base predictions on those future frames.

Abstract: Examples are described for mapping primitives in circular images, generated from texture coordinate that compensate for rotation of cameras, onto respective mesh models to generate images representative of a 360-degree video or image. Portions of the rectangular images are blended to generate a stitched rectangular image, and image content for display is generated based on the stitched rectangular image.

Abstract: Examples are described for overlaying circular images onto a three-dimensional mesh model to generated respective portions of image content for 360-degree viewable content, where each of the portions is a sub-capsule that is larger than half of the sphere. The portions are rendered and then blended based on overlapping portions of the image content from the 360-degree viewable content.

Abstract: A vibrational multi-morph piezoelectric energy harvester includes a composite shim having a parallelepiped form with a thickness dimension made smaller than width and length dimensions, and having a stiffness shifting from one extremity to the other extremity to minimize mechanical constraints developed at a clamping area; a seismic mass mounted at an end opposite to the clamping area to mechanically match the system to the surrounding vibration resonance; one or more piezoelectric layers laminated on said composite shim; and electrodes plated onto the one or more piezoelectric layers for connection to an electronic harvesting circuit, a battery, or a super capacitor.

Abstract: A method for identifying a shared credential within a networked computing environment. The method includes a computer processor accessing information corresponding to an aggregated plurality of authentication events within a networked computing environment. The method further includes identifying one or more credentials that are associated with the aggregated plurality of authentication events. The method further includes analyzing a frequency of usage of a first credential that is included in the identified one or more credentials. The method further includes determining that the first credential is shared, based at least in part, on the analysis of the frequency of usage of the first credential in authentication events by one or more hosts, and information related to authentication events corresponding to the one or more hosts that utilize the credential in authentication events. The method further includes generating a report that identifies that the first credential is shared.

Abstract: Techniques are described related to generating image content. A graphics processing unit (GPU) is configured to receive a first set of images generated from a first camera device in a first location, the first camera device having a first orientation, render for display the first set of images oriented to an orientation reference, receive a second, different set of images generated from a second, different camera device in a second, different location, the second camera device having a second orientation, the second orientation being different than the first orientation, and render for display the second set of images oriented to the orientation reference.

Abstract: At least one processor may retrieve from a framebuffer a depth value associated with a pixel. The at least one processor may determine whether a fragment depth value associated with a fragment of a splat is within a non-zero offset of the depth value associated with the pixel. Responsive to determining that the fragment depth value associated with the fragment of the splat is within the non-zero offset of the depth value associated with the pixel, the at least one processor may output updated data for the pixel to the framebuffer based at least in part on data associated with the fragment of the splat.

Abstract: A method for implement an energy-efficient user access control to wireless sensor networks is disclosed. A user creates a secret key and sending it to a sensor. The sensor builds a first MAC value by the secret key and sends it to the Key Distribution Center which builds a second MAC value and sending it to the sensor. The sensor decrypts the second MAC value to get a random number, and builds a third MAC value by the random number. The third MAC value is used by the user to authenticate the sensor.
