Abstract - Image fusion is defined as combining useful
information from multiple images to a single image. The resulting image will be more informative and accurate. Image fusion not only just combines images but also constructs images such that the information produced is understandable from human and machine perception. The satellites capture images by the high resolution camera and by the help of concepts of remote sensing. Remote sensing is the process of gathering the information of an object without making a physical contact with the object. This paper uses the hybrid fusion technique which is composed of both spatial and frequency domains. This paper is based on the concept of satellite image fusion as an application of hybrid fusion technique.

1. INTRODUCTION Image fusion combines multisensor data to produce a fused image with high spatial, spectral, and radiometric resolutions. Image fusion is the most beneficial technology in remote sensing for utilizing multisensor, multispectral earth observation satellites at varying resolutions. Spatial resolution is critical for delineating objects in a remote sensing picture. The characteristics of a high spatial resolution image with multispectral information are easier to comprehend than a single high resolution Pan image. The single output image is more informative and accurate than any of the single source image and it consists of all necessary information
Fig -2: Image Mixing Image fusion can help in restoration of degraded images and mixing images. By using the hybrid fusion technique, the image quality will be super enhanced in terms of both spatial and frequency domains. Image fusion is used in various fields like computer vision, remote sensing and medical imaging.
Image restoration: Image fusion can be used to restore an image from more than one degraded images with uncommon areas of degradation.
Image fusion can be broadly classified into two types: Spatial domain fusion and Transform (Frequency) domain fusion. In spatial domain the operations are done directly on pixels of the image to get the desired image whereas in the Transform domain the operations are done on Fourier transform of the image followed by Inverse Fourier transform to get the resultant image.
