DWT-Based Image Fusion Technique in Matlab: Identifying the most effective method

Abstract

Images have some information that can be perceived by the value or intensity of pixel colors or through their visual appearance, used in medical imaging which is used for medical management to generate a visual representation of the inside functioning of the human body. CT and MRI go through medical imaging techniques that provide valuable information to treat medical conditions. The fused image gives a complete analysis of a patient’s body by revealing the internal structure with comprehensive information through computer processing. In previous research, this process of fusing two images was approached using a specified DWT technique. In this paper, we demonstrate the best image fusion method for a DWT technique so that it can provide a fused image with significant detail. Image fusion can be implemented using Discrete Wavelet Transform techniques, which include nine combinations of Mean-Max-Min fusion methods. The analysis to derive the best fusion method and implementation of the image fusion method using the DWT technique is done using Matlab programming.
