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

Figure 5

Result showing the independency of with time : (a) sequential synthetic images for myocardial motion. The first row shows the synthetic initial image and the tracking points representing the sequential motion of heart, the second row the sequential images corresponding to the motion of the tracking points, and the last row the tracking points (yellow “o” marks) and LV contour (yellow dotted line) by the displacements computed using and the mean value of computed using the sequential images. (b) The change of according to . The value varies within the range of .
