Fast and Efficient Zero-Learning Image Fusion
We propose a real-time image fusion method using pre-trained neural networks.
Our method generates a single image containing features from multiple sources.
We first decompose images into a base layer representing large scale intensity
variations, and a detail layer containing small scale changes. We use visual
saliency to fuse the base layers, and deep feature maps extracted from a
pre-trained neural network to fuse the detail layers. We conduct ablation
studies to analyze our method's parameters such as decomposition filters,
weight construction methods, and network depth and architecture. Then, we
validate its effectiveness and speed on thermal, medical, and multi-focus
fusion. We also apply it to multiple image inputs such as multi-exposure
sequences. The experimental results demonstrate that our technique achieves
state-of-the-art performance in visual quality, objective assessment, and
runtime efficiency.Comment: 13 pages, 10 figure
