摘要： A method for managing Virtual Machine (VM) storage space is provided. In the method, a Storage Balloon Agent (SBA) module deployed in a VM is adopted to directly acquire virtual storage free block information and deliver the acquired virtual storage free block information to a Storage Balloon Daemon (SBD) module deployed in a Virtual Machine Monitor (VMM) layer; and the SBD module releases a part or all of physical storage space corresponding to the virtual storage free block information, and marks virtual storage blocks corresponding to the released physical storage space as unavailable. A corresponding system and a physical host are further provided in the present invention. Through the method of an embodiment of the present invention, use condition of virtual storage space can be acquired in real time, and a large number of read and write operations of a storage system can be avoided. The method is applicable to both a virtual storage system in a dynamic allocation format and a virtual storage system in a pre-allocation format.

摘要： An image processing method and apparatus are disclosed. The method includes: obtaining multiple video frames, where the multiple video frames are collected from a same scene at different angles; 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; 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 videos. Because a video frame image is supplemented before a browsing frame is generated, a speed in image browsing is improved with integrity of a browsed image ensured.
