Abstract: Many enhancement methods have been proposed earlier to enhance satellite images. Most of them have critical and more advance steps still those methods unable to give satisfied result. One of the necessary issues regarding to the satellite images is to sharpen the edges, as edges are helpful in identifying important information from the images. So new method is proposed in this paper regarding to detect and enhance the edges of satellite images. Also the noise removal and preservation of useful information are other important aspects of this work. In this work Gabor filter is used for efficiently detects the edges from image, while morphological filtering applies on that detected edges to sharpen it. This method gives better qualitative and quantitative result compare to the well known state-of- the-art techniques.
