Robust Myocardial Motion Tracking for Echocardiography: Variational Framework Integrating Local-to-Global Deformation

Figure 7

Case I: real images with weak signals in endocardial border. The second and third rows are the results by region-based tracking methods using sum-of-squared difference (SSD) and cross-correlation, respectively. The fourth row is the result by the LK optical flow and the final row is the result by the proposed method ( ).
