Multi-Scale and Shape Constrained Localized Region-Based Active Contour Segmentation of Uterine Fibroid Ultrasound Images in HIFU Therapy
Figure 7
Effects of different localizing radii on the segmentation results.
The first row and the second row present the segmentation results with different localizing radii using the LCV model and the MSLCV model, respectively. The green curves are manual segmentation results by the specialist, the red curves are the results from the experiments, and the yellow circles represent the size of localized regions formed by the localizing radius. The localizing radii of (a) and (d), (b) and (e), and (c) and (f) are 4, 20 and 45, respectively.
