Image Fusion of Remote Sensing Kerala Flood Images based on DWT with Multiple Wavelet Families

Abstract

Image fusion plays a key role in image processing for retaining the required information from various images. This paper presents overall view of an image fusion process of remote sensing images based on DWT with multiple wavelets family. These two images are acquired at different timings by using Sentinel-2 with SAR sensor. Testing images are Kerala flood images which are occurred in the year of 2018. In this regard various types of wavelets filter coefficients such as Haar wavelet, Daubechies wavelet coefficients (db2), Symlets coefficients, Coiflets coefficients have been employed for performing the image fusion. MATLAB 2017a tool has been used for simulation purpose.
