From the obtained results, the nearly piecewise-constant optimal treatment (optimal control) was calculated and plotted in Figure 1.
1] element of Rannacher and Turek [18] for the velocity and piecewise-constant for the pressure.
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.

Alternatively, we can define images as piecewise-constant functions on the half-open interval [0,1).
