Segmentation results during end-systole. Each image represents the results after varying an individual model parameter. (a) Initialization of model during end-systole as oppose to early-systole, (b) decreased user guide points from 8 to 4 per short axis slice, (c) model mesh size is increased from 32 to 64 elements and (d) smoothing weight factors reduced from α = 0.1 × 10^-1 to 0.1 × 10^-3 and β = 0.2 × 10^-1 to 0.2 × 10^-3.
