Advances in digital image processing technology have increased the need for image fusion techniques to produce more accurate and high-quality visual information. This study aims to analyze methodological developments, research trends, datasets, evaluation methods, and challenges in image fusion research through a Systematic Literature Review (SLR) using the PRISMA framework. The literature selection process resulted in 335 papers being included for analysis. The findings indicate that deep learning-based methods, particularly Convolutional Neural Networks (CNNs), have become the dominant approach in modern image fusion research. Furthermore, recent studies have increasingly explored Generative Adversarial Networks (GANs), Transformers, and hybrid methods to improve fusion performance. The most significant challenges identified include the need for large-scale datasets, high computational complexity, the lack of standardized evaluation frameworks, and limitations in model generalization. These findings provide a comprehensive overview of current developments and highlight future research opportunities in deep learning-based image fusion.
