Problems solved by technology

However, the traditional multi-scale image fusion method is implemented in the frequency domain, which has high computational complexity and cannot meet the real-time requirements of the system. The proposed two-scale spatial domain transformation image fusion method improves the fusion efficiency, but the existing two-scale Method processing images prone to noise

Abstract

The invention relates to an image fusion method and system. The method comprises the steps: obtaining a source image, wherein the source image comprises a fluorescence image and a visible light image;carrying out two-scale decomposition on the source image by adopting a Gaussian filtering method to obtain a base layer image and a detail layer image of the source image; constructing a weight map of the highlighted fluorescence information by using a nonlinear function; fusing the base layer image corresponding to the fluorescence image and the base layer image corresponding to the visible light image to obtain a base layer image of a fused image; constructing a second weight map for enhancing fluorescence information based on significance detection; fusing the detail layer image corresponding to the fluorescence image and the detail layer image corresponding to the visible light image to obtain a detail layer image of the fused image; and reconstructing the base layer image of the fused image and the detail layer image of the fused image to obtain a fused image. According to the invention, the complexity of a multi-scale algorithm can be reduced, and the image fusion efficiency isimproved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image fusion method and system. Background technique [0002] Image fusion technology is the synthesis of two or more images of the same scene under different spectral and spatial details. In the perceptual evaluation of different image fusion schemes, Toet et al pointed out that infrared images have the best effect on target detection and recognition, while visible light images have the best effect on global scene perception. Therefore, the comprehensive use of complementary information between visible light images and infrared images It is fused into a new image and provides richer information. It has important applications in research fields such as target recognition, multi-source information mining, medical imaging, and map matching. [0003] Because the multi-scale geometric analysis method conforms to the visual characteristics of human beings, and the...
