From the obtained results, the nearly piecewise-constant
optimal treatment (optimal control) was calculated and plotted in Figure 1.
Traditionally, to impose the piecewise-constant
property of medical images the role of sparse-promoted penalty is usually assigned to the total variation (TV) regularization.
1] element of Rannacher and Turek  for the velocity and piecewise-constant

1 and with the normal-vector field with a piecewise-constant
We point out that it is possible to show that the non-linear diffusion equation is equivalent to a robust procedure that estimates a piecewise-constant
image from a noisy input image (Sapiro, 2001).
We introduce and study in this paper piecewise-constant
framelets (PCF) that include the Haar system as a special case.
A standard first-order scheme would use the piecewise-constant
solution on either side of the edge as the upwind values, e.
