To solve the issues with conventional level set segmentation algorithms, which are sensitive to initial contours and less noise-resistant, a model based on coupling of texture information structural is developed. In this model, rotation invariant mask produced by fractional-order differentiation used first describe image’s global information. Then, power function energy generalization solved ap...

A finite element based level set method is proposed for structural topology optimization. Because both the level set equation and the reinitialization equation are advection dominated partial differential equations, the standard Galerkin finite element method may produce oscillating results. In this paper, both equations are solved using a streamline diffusion finite element method (SDFEM). The...
