Patent number: 11645765Abstract: 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.Type: GrantFiled: December 21, 2021Date of Patent: May 9, 2023Assignee: AltumView Systems Inc.Inventors: Yu Gao, Xing Wang, Rui Ma, Chao Shen, Minghua Chen, Jie Liang, Jianbing Wu
