Fusion of IR and Visual Images Based on Gaussian and Laplacian Decomposition Using Histogram Distributions and Edge Selection

Abstract EN

We propose a novel fusion method of IR (infrared) and visual images to combine distinct information from two sources.

To decompose an image into its low and high frequency components, we use Gaussian and Laplacian decomposition.

The strong high frequency information in the two sources can be easily fused by selecting the large magnitude of Laplacian images.

The distinct low frequency information, however, is not as easily determined.

As such, we use histogram distributions of the two sources.

Therefore, experimental results show that the fused images can contain the dominant characteristics of both sources.
