Image fusion method and device based on latent low-rank representation and structure tensor

Abstract

The image fusion method and device based on latent low-rank representation and structure tensor provided by the present invention aims at the shortcomings of the existing dual-channel PCNN model in solving the fusion problem of infrared images and visible light images, and utilizes the LSR operator based on the LatLRR algorithm As the external stimulus of the PCNN model, it solves the large difference between the infrared image and the visible light image, and uses the TSV operator based on the structural tensor singular value decomposition as the link strength to characterize the feature change of the image. To a certain extent, it can It solves the problem of low contrast of the fusion image due to the large spectral difference between the infrared image and the visible light image, and at the same time retains rich texture information and detail information more completely, and the image transition is natural.

Description

technical field [0001] The invention relates to the field of image fusion, in particular to an image fusion method and device based on latent low-rank representation and structure tensor. Background technique [0002] With the continuous development of digital image processing technology and data fusion technology, the research on infrared (IR) and visible light (VI) image fusion technology has gradually become a research hotspot. The fusion of infrared and visible light images is to combine the salient features of infrared images with the gradient texture features of visible light images, which is conducive to faster and more accurate detection of targets in the case of concealment, camouflage and confusion. Since the fused image can combine the advantages of the source images, this technology has been widely used in military reconnaissance, computer vision, security monitoring and other fields. [0003] For the fusion between IR and VI images, there are currently two main...
