摘要： Examples include a processor including fetch circuitry to fetch a guest physical address translation instruction having a format with fields to specify at least an opcode and locations of a source vector and a destination vector, decode circuitry to decode the fetched guest physical address translation instruction, and execution circuitry to execute the decoded guest physical address translation instruction. Execution of the decoded guest physical address translation instruction includes comparing guest physical addresses of the source vector with base and end addresses of a selected memory region, masking a guest physical address of the source vector if the guest physical address is in the selected memory region, translating the masked guest physical addresses into host addresses, and storing the host addresses into the destination vector.

摘要： 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.

摘要： 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.
