Odd-Ary Approximating Subdivision Schemes and RS Strategy for Irregular Dense Initial Data

Figure 1

(a) Initial polygon (noisy or irregular data points) and curves generated by 3-point ternary scheme (4th level) in (2.3) with mask 𝛼^33,4 and (b) same initial polygon and curve generated by 5-point ternary scheme (4th level) in (2.4) with mask 𝛼^35,7. Oscillations at 4th level of subdivision schemes are significant.
