Image Zooming by Combination of the Curvature-driven and Edge-stopping Nonlinear Diffusion
曲率驱动与边缘停止相结合的图像放大

Based on the good performances of nonlinear diffusion in preserving important image features, the Curvature driven with Edge-stopping(C& E model) was proposed and applied into image zooming. The C& E model has the proteclion of little curvature and big gradient is emphasized, at same time, it has two effects of connecting broken isophotes and strengthening edge. hhe condition of the initial and boundary value of image zooming, as well as numerical schemes,were further discussed. For image zooming, the C&E model exhibits better performance than the nonlinear diffusion model.
