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

Figure 8

Case II: real images with indistinguishable speckle patterns 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 fifth row by the proposed method ( ).
