Abstract: Technologies are generally described for a system and method for assigning a task in a cloud. In some examples, the method may include receiving a task request relating to a task and determining service related data relating to the task based on the task request. In some examples, the method may include receiving resource data relating to a first and second resource in the cloud. In some examples, the method may include determining a first correlation value between the task and the first resource and a second correlation value between the task and the second resource based on the service related data and the resource data. In some examples, the method may include assigning the task to the first resource based on the first and second correlation value.

Abstract: Techniques related to identifying objects in a video are generally described. One example method for identifying a moving object in a video may include generating a background frame and a foreground frame based on the video, comparing the foreground and the background frames at each corresponding location, acquiring an object area based on the comparison, determining if object area contains a moving object based on size and shape of the object area, identifying the moving object against templates of target objects, and updating the background frame according to the comparison.
