In a recent work, the Modified Explicit Decoupled Group (MEDG) method was formulated as an addition to the family of four-point explicit group methods in solving the Poisson equation. The method was formulated using a combination of the rotated five-point finite difference approximation on the √(2h) grid stencil together with the five-point centred difference approximation on the h and 2h grid stencils...
With respect to the problem that it is very difficult for the existing image mosaic algorithms to be adaptive for the big gray difference between the to-be-mosaic images, a novel image mosaic algorithm based on the method of finite difference is proposed, in order to make the boundary area near the seam smooth and to keep the coincidence of globe intensity in a resultant mosaic image. Firstly, an...
