Image processing has been used in wider application. To process the images, Mat lab has become one of the most inevitable tool. But to use the MATLAB effectively the original software is required. This problem can be overridden by Open source software like SciLab. This paper gives the overview of scilab and it variants relevant to mat lab for a case study. We proposed image fusion application as a case study. This paper will contain short and crisp about the image processing with mat lab and the fusion techniques. The results were discussed with its sample output. This paper is organized as follows: It starts with an introduction, basic filtering process and followed by an enhancement. Last section deals with the fusion of images using mat lab.
