Sub-Regional Infrared-Visible Image Fusion Using Multi-Scale Transformation

Abstract

Infrared-visible image fusion plays an important role in multi-source data fusion, which has the advantage of integrating useful information from multi-source sensors. However, there are still challenges in target enhancement and visual improvement. To deal with these problems, a sub-regional infrared-visible image fusion method (SRF) is proposed. First, morphology and threshold segmentation is applied to extract targets interested in infrared images. Second, the infrared background is reconstructed based on extracted targets and the visible image. Finally, target and background regions are fused using a multi-scale transform. Experimental results are obtained using public data for comparison and evaluation, which demonstrate that the proposed SRF has potential benefits over other methods.
