Abstract: An image processing method includes obtaining multiple video frames, where the multiple video frames are collected from a same scene at different angles and determining a depth map of each video frame according to corresponding pixels among the multiple video frames; supplementing background missing regions of the multiple video frames according to depth maps of the multiple video frames, to obtain supplemented video frames of the multiple video frames and depth maps of the multiple supplemented video frames. The method also includes generating an alpha image of each video frame according to an occlusion relationship between each of the multiple video frames and a supplemented video frame of each video frame in a background missing region and generating a browsing frame at a specified browsing angle according to the multiple video frames, the supplemented video frames of the multiple video frames, and alpha images of the multiple video frames.

Abstract: The present application discloses an image enlargement method and apparatus. The method includes: inputting a low-resolution image, where the low-resolution image includes at least one matching areas; searching one of the matching areas for an optimal contour template, where the optimal contour template is a contour template with a minimum total variation value in the matching area and the contour template set; finding a second pixel point according to a zoom ratio and a first pixel point in the matching area; performing local interpolation for the second pixel point according to the optimal contour template, so as to obtain an intermediate pixel value; repeating the foregoing steps until processing for all the matching areas is complete, and obtaining an initial high-resolution image according to all of the intermediate pixel values; and performing global interpolation for the initial high-resolution image to obtain a high-resolution image.

Abstract: A virtualization processing method and apparatuses, and a computer system are provided. Where a computing node includes: a hardware layer, a Host running on the hardware layer, and at least one virtual machine (VM) running on the Host, the hardware layer includes an I/O device, several corresponding virtual function (VF) devices are virtualized from the I/O device, the Host has several VF software instances, the several VF software instances and the several VF devices are in one-to-one correspondence; the Host further has a back-end instance (BE) of an I/O virtual device having the same type with the I/O device, the VM has a front-end instance (FE) of the I/O virtual device; the BE in the Host is bound with an idle VF software instance. The solutions of the embodiments of the present invention are beneficial to optimization of the performance and compatibility of a virtualization system.
