Abstract: Techniques related to generating a virtual view of a scene from a position between positions of known input images for presentation to a viewer are discussed. Such techniques include applying a convolution mask that approximates an inverse of a linear combination of at least the horizontal and vertical convolution matrices representative of gradient detection in the input images to a virtual intermediate gradient image that is a combination of at least an interpolated virtual image at the position, an interpolated horizontal gradient map at the position, and an interpolated vertical gradient map at the position to generate a final virtual image for the position.

Abstract: There is disclosed in one example a computing apparatus, including: a hardware platform configured to communicatively couple with a multi-tenant cloud service, the multi-tenant cloud service including an oversubscribable resource; and a service assurance for oversubscribable resource (SAOR) engine configured to: receive tenant subscriptions to the oversubscribable resource, wherein tenant subscriptions exceed available instances of the oversubscribable resource; receive per-tenant quality of service (QoS) metrics for the oversubscribable resource; receive an allocation request from a guest for allocation of an instance of the oversubscribable resource; compare the request to currently-available instances of the oversubscribable resource; determine that the oversubscribable resource has capacity to service the request according to the QoS metrics of the tenant; and allocate an instance of the oversubscribable resource to the guest.

Abstract: Techniques related to image rectification for fisheye images are discussed. Such techniques may include iteratively determining warpings for equirectangular images corresponding to the fisheye images using alternating feature mappings between neighboring ones of the equirectangular images until mean vertical disparities between the features are reduced below a threshold, and warping the equirectangular images to rectified equirectangular images.

Abstract: Techniques related to calibrating fisheye cameras using a single image are discussed. Such techniques include applying a first pretrained convolutional neural network to an input fisheye image to generate camera model parameters excluding a principle point and applying a second pretrained convolutional neural network to the fisheye image and a difference of the fisheye image and a projection of the fisheye image using the camera model parameters to generate the principle point.

Abstract: An example system for generating stereoscopic light field panoramas includes a receiver to receive a plurality of synchronized images. The system also includes a calibrator and projector to calibrate the synchronized images, undistort the synchronized images, and project the undistorted images to a sphere to generate undistorted rectilinear images. The system further includes a disparity estimator to estimate a disparity between neighboring views of the undistorted rectilinear images to determine an optical flow between the undistorted rectilinear images. The system includes a view interpolator to perform in-between view interpolation on the undistorted rectilinear images based on the optical flow. The system also further includes a light field panorama generator to generate a stereoscopic light field panorama for a plurality of perspectives using concentric viewing circles.

Abstract: Techniques related to interpolating an intermediate view image from multi-view images are discussed. Such techniques include downsampling first and second images that represent a view of a scene, generating a disparity map based on applying a first CNN to the downscaled first and second images, translating the downscaled first and second images using the disparity map, applying a second CNN to the translated downscaled first and second images and the disparity map to generate a downscaled intermediate image, and upscaling the downscaled intermediate image to an intermediate image at the resolution of the first and second images using an image super-resolution convolutional neural network.

Abstract: Various systems and methods for implementing protocol state aware power management are described herein. A network interface device for implementing protocol state aware power management includes circuitry to provide a direct memory access interface; medium access control (MAC) circuitry to interface with a network; and control circuitry to: classify packets received at the MAC circuitry as packets used to open network connections or packets used to close network connections; maintain statistics of packets used to open network connections and packets used to close network connections; calculate a power hint based on the statistics of packets used to open connections and packets used to close network connections; and write a receive descriptor to a host memory using the direct memory access interface, the receive descriptor including a power hint field with the power hint, the power hint used by a host processor to scale processor power based on the power hint.
