Paper Abstract

Two methods are used for curve evolving, which are based on PDE (Partial Differential Equation)(level set method) and discrete median filter. Comparisons between the evolving methodology, target and time cost, together with the experiment results show that the former can ensure the good convergence with certain time step, but the run speed is relatively slow; the latter can also be expressed by PDE, so it can smooth the edge, and the convergence speed is very fast. In short, the former is a power tool in image segmentation and image filtering, while the latter fits for image filtering.
