Alternative Parametric Boundary Reconstruction Method for Biomedical Imaging

Figure 4

Recovery of the boundary of the star specified by 100 points: 10 along each arm with Gaussian noise of 𝜈=4. The boundary is constructed using approximate interpolation, using 𝜎_𝐴=1×10⁻⁶ and 𝜎_𝐵=1×10⁻⁴. The recovered curve is shown as a thicker line.
