Patent number: 9734587Abstract: In some implementations, a computing device can track an object from a first image frame to a second image frame using a self-correcting tracking method. The computing device can select points of interest in the first image frame. The computing device can track the selected points of interest from the first image frame to the second image frame using optical flow object tracking. The computing device can prune the matching pairs of points and generate a transform based on the remaining matching pairs to detect the selected object in the second image frame. The computing device can generate a tracking confidence metric based on a projection error for each point of interest tracked from the first frame to the second frame. The computing device can correct tracking errors by reacquiring the object when the tracking confidence metric is below a threshold value.Type: GrantFiled: September 30, 2015Date of Patent: August 15, 2017Assignee: APPLE INC.Inventors: Zehang Sun, Toshihiro Horie, Xin Tong, Peter Chou
