Alternative Parametric Boundary Reconstruction Method for Biomedical Imaging

Figure 2

Recovery of the boundary of disk specified by 96 points with Gaussian noise of 𝜈=3, starting at (1,0) on the 𝑥-axis and moving counterclockwise around the circle with the boundary recovered using approximate interpolation, with 𝜎_𝐴=1×10⁻⁶ and 𝜎_𝐵=1×10⁻⁴. The recovered curve is shown as a thicker line.
