摘要
Abstract
On the basis of the continuous equation of image fusion based on Partial Differentiation Equations(PDE)proposed by Pop.S et al, a new numerical scheme of the equation is presented. The former discrete scheme of divergence by the calcula-tion of gradient is changed to the scheme of the calculation of Laplace, and the regularization term of equation is also adjusted accordingly. The comparison experiments are designed for two schemes on some 1D and 2D signals. The results show that the new scheme can perform the fusion effectively for all the tested signals;and the new scheme can accelerate the convergence process and make the quality of fused image improved by means of a quality factor for some of the tested 1D and 2D signals. However for the other tested signals, the convergence and the quality of output signals obtained by both the new scheme and the former scheme are also very much closed.关键词
