Abstract

The invention provides an image fusion method and a device of total variational and structural tensor. The total variational TV model obtains a target gradient field of the fusion image by using the structural tensor of the image, and utilizes Soft. The Max function softens the weight of the gradient field, the fusion gradient field is put into the regular term of TV model, ensuring that the gradient field of the fusion image is close to the target gradient field, The splitting Bregman algorithm is used to solve the new TV model, The final fusion image can be obtained. By adopting this scheme,the features of the image can be expressed better, the texture information of low-light level and the salient features of infrared image can be combined perfectly, and the better fusion effect can beobtained. The abundant texture information and detail information can be completely retained, 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 of total variation and structure tensor. Background technique [0002] As a branch of information fusion, image fusion is a comprehensive high-tech including signal processing, image processing, computer technology, image detector technology and other fields. Image fusion extracts information from multiple images acquired in a certain scene, and finally synthesizes two or more images containing diverse and redundant information into a new image with richer information. Fused images overcome the limitations of a single image in terms of spatial resolution, physical properties, temporal resolution, and spectral information, and can better support the positioning, identification, and understanding of important targets. [0003] Information fusion between infrared (IR) and visible light (VI) sensors is currently the most widely used and most practical fu...
