Advantages: It is less likely to be affected by noise, compensates the holes or missing boundaries, and can estimate the missing LI interface boundary. Limitations: The method would work fine for early thickening of IMC but fails for irregular boundaries in the presence of plaques and eliminates minor details.
Advantages: Robust to a reasonable variability in the initialization, lowest tracing error for LI & MA, method is not sensitive to the degree of stenosis or calcification. Limitations: Depends on initial segmentation
Advantages: Reasonable average computation time, robust to the estimation procedures. Limitations: Method suitable for healthy arteries, extensive tuning & training, so computational cost is high, for different scanner requires retraining & retuning.
Advantages: No initial human setting, capable of processing images of different quality, ambiguous cases user can intervene, and reduced interobserver variability. Limitations: Training required, for different scanner retraining needed, searched LI & MA interfaces may cross each other.
Advantages: Fully automated, low computational complexity; suitable for clinical purposes, human correction allowed. Limitations: Initial human setting & training required, fails for slanting IMC with weak boundary.
