An investigation in satellite images based on image enhancement techniques

In Satellite Images, enhancement plays a dynamic research topic in image processing. The aim of enhancement is to process an image so that the result is more suitable than original image for specific remote sensing application. Satellite image enhancement techniques provide a lot of choices for improving the visual quality of remotely sensed images. In this research review, image fusion plays an important role, since it effectively combines auxiliary image content to enhance information contained in the individual datasets. This article provides an overview of the existing enhancement techniques. There are many techniques which have been proposed for enhancing the digital images which may be used for enhancing Satellite images. Here, a survey on various Satellite image enhancement techniques has been performed which recommends fusion-based enhancement performs superior while comparing with non-fusion-based enhancement techniques.
