Active contour models without edges

Figure 4.2: Comparisons on the real image. Top: original image u and noisy

version. Middle: results (it,v) obtained with the Ambrosio-Tortorelli and Shah

approximations. Bottom: results (w,v) obtained with our reduced models for

p = 1; 1.5; 2. Again, the reduced models produce better reconstruction, and

with sharper edges.
