Abstract: Features of each ordered step of a recorded test script for an application under test (AUT) are generated. The ordered steps are segmentally organized over actions based on feature relatedness of the ordered steps. Each action includes a contiguous subset of the ordered steps. The actions are hierarchically organized within a tree based on an ordered feature relatedness of the actions. The tree has nodes respectively corresponding to the actions. The actions are abstractedly related to one another based on an unordered feature relatedness of the actions to generate abstracted actions that each generalize a subset of the actions. Abstracted action groups are generated based on the abstracted actions and the tree. Each abstracted action group includes abstracted actions mapping to corresponding nodes of the tree within a same branch. The ordered steps of the recorded test script are collapsed into a series of instantiations of the abstracted action groups.

Abstract: Embodiments described herein provide various examples of real-time visual object tracking. In another aspect, a process for performing a local re-identification of a target object which was earlier detected in a video but later lost when tracking the target object is disclosed. This process begins by receiving a current video frame of the video and a predicted location of the target object. The process then places a current search window in the current video frame centered on or in the vicinity of the predicted location of the target object. Next, the process extracts a feature map from an image patch within the current search window. The process further retrieves a set of stored feature maps computed at a set of previously-determined locations of the target object from a set of previously-processed video frames in the video. The process next computes a set of correlation maps between the feature map and each of the set of stored feature maps.
