Abstract: An image processing system, method, and apparatus are provided and pertain to the field of information technologies. The method includes receiving an image processing instruction sent by a data source manager, the image processing instruction triggered by an application client and instructing to process an image obtained by an image input device corresponding to a general-purpose data source; processing, according to the image processing instruction, the image obtained by the image input device; and sending a processing result to the data source manager. According to the application, the general-purpose data source processes the image obtained by the image input device, thereby avoiding a problem that the image obtained by the image input device cannot be processed because the image input device does not provide a data source.

Abstract: A desktop cloud virtual machine access method includes receiving, by a desktop cloud controller, an access request from a desktop cloud client, where a target virtual machine (VM) specified in the access request is deployed on a target computing node, and then, when determining that a target virtual access gateway (VAG) is deployed on the target computing node, instructing, by the desktop cloud controller, the desktop cloud client to establish communication with the target virtual machine using the target virtual access gateway.

Abstract: A universal serial bus (USB) device access method, apparatus and system, a terminal, and a server are provided. The method, executed by a terminal, includes receiving an access request delivered by a server; if the access request instructs the terminal to perform the first access operation on the physical USB device, performing a first processing operation corresponding to the first access operation according to a compatibility policy, so as to feedback an execution result of the first processing operation to the server. The terminal performs the first processing operation by responding to the first access operation when the physical USB device does not support the first access operation therefore ensuring that a user properly uses the physical USB device.
