Abstract

The invention relates to an infrared and visible light image fusion method based on area sparse representation. The method comprises the steps of firstly performing blocking on an infrared and visible image; then searching a consistent area in which each image block exists, performing combined sparse coding on the consistent area and calculating a significance measure; and finally performing weighted fusion on corresponding image blocks according to the significance measure, and assembling all fusing image blocks for obtaining a fused image. Compared with the prior art, the infrared and visible light image fusion method has advantages of storing structure information which is locally insignificant and is non-locally significant, effectively improving structure integrity and area consistency of the fused image, etc.

Description

technical field [0001] The invention relates to an image fusion method, in particular to an infrared and visible light image fusion method based on region sparse representation. Background technique [0002] Image fusion can synthesize multiple images about a specific scene and present them to the observer or for further processing in a manner that meets specific task requirements. Image fusion can make information cover a wider range of space and time, reduce the redundancy and uncertainty of information, and improve the complementarity and reliability of information. It has important applications in the fields of civil and national defense. Fusion of infrared image and visible light image is an important aspect of multi-source image fusion. Infrared images can provide more target information, and visible light images can provide more background information, and the fusion of the two can significantly improve the cognitive performance of the observer. [0003] Image fusio...
