Embodiment Construction

[0028] A preferred embodiment of the present invention is described as follows in conjunction with the drawings:

[0029] This is a visible light and infrared image fusion method based on Contourlet transform, such as figure 1 As shown, based on the multi-scale and multi-directional Contourlet decomposition of the input visible light and infrared images, the different characteristics of the visible light and infrared images are used to use different fusion strategies for the high-frequency detail part and the low-frequency background part to generate the Contourlet domain The fusion coefficients are finally obtained through the Contourlet inverse transformation to obtain the fusion image.

[0030] The specific steps are:

[0031] (1) Based on the registration of the visible light and infrared images of the same scene, the input visible light image I Vis And infrared image I Inf Perform multi-scale and multi-directional Contourlet transformation, and each image is decomposed into ...

Abstract

A method for fusing visible light with infrared-ray image based on contourlet transform generates fusion coefficient of contourlet domain by utilizing different characteristic of visible light and infrared-ray image and by utilizing different fusion policy of high frequency detailed portion and low frequency background portion based on contourlet decomposition of inputted visible light and infrared-ray image then obtains fused image through contourlet counter transform.

Description

Technical field [0001] The invention relates to a visible light and infrared image fusion method based on Contourlet (contour wavelet) transformation. It is a multi-sensor image information fusion method in the field of information fusion. It is used in military and non-military fields such as optical imaging, target detection, and security It is widely used in monitoring and other systems. Background technique [0002] Multi-sensor image fusion is to make full use of the complementary image information provided by different imaging systems to fuse various complementary information of the same scene obtained by different types of sensors to generate new image signals. It increases the amount of information in the image, improves the adaptability of the image to the environment, obtains more accurate, more comprehensive, and more reliable useful information, and provides a reliable and clear image for further processing. Image fusion technology is an emerging technology that integ...
