Dice Coefficients and 95% Hausdorff Distance of the Proposed Method and the Method in [54]. Third, Eleventh, Twelve, and Thirteenth Testing Images are T2 Images Where the Bladder is Very Bright. Hence the Chan-Vese Model Used in [54] Extracts the Bladder Region Instead of Prostate. In Computing the Mean/Standard Deviation, Those Cases are Not Counted
