Fusing Infrared and Visible Images: A New Approach

Infrared and visible light image fusion is a hot topic in computer vision. It's all about combining the strengths of both types of images to get a better overall picture. Traditional methods have had some issues. They often struggle with extracting all the important features, lose detailed textures, and don't make the most of the unique and shared information in the images. Plus, they can be quite demanding on computational resources. One innovative solution tackles these problems head-on. It uses a two-branch system to interact with features at multiple scales. This approach is designed to be lightweight, meaning it doesn't need as many parameters as other methods. It does this by using group convolutions and stacking small convolutional kernels. This setup helps to enhance the interaction of multi-scale information while keeping the model efficient. The method also improves on multi-level attention modules. It adds edge-enhanced branches and depthwise separable convolutions. These additions help to preserve the detailed texture information that can often get lost in the fusion process. Think of it like trying to capture every little detail in a high-resolution photo. Another key part of this approach is the cross-attention fusion module. This module is designed to optimize the use of both differential and shared features. It does this while keeping computational complexity to a minimum. It's like having a smart assistant that knows exactly what information to focus on and what to ignore. To top it all off, the method includes a multi-dimensional fusion branch. This branch boosts the interaction of information across multiple dimensions. It helps to extract comprehensive spatial information from the multimodal images. This is crucial for tasks that require a deep understanding of the scene, like target detection. The proposed method was put to the test against seven other algorithms. It was evaluated on public datasets like TNO and Roadscene. The results were impressive. The method outperformed the others in both subjective and objective evaluations. It also showed good operational efficiency. Further experiments on the
