Tracking results for simulated data, horizontal motion only. Three simulated images at time frames (a) t = 1, (b) t = 2, and (c) t = 3. Displacement fields (horizontal only, in units of pixels) from the first to the second time frames: (d) the true field, (e) that computed using traditional HARP tracking, and (f) that computed using SP-HR.
