Abstract

The invention discloses an image fusion method based on joint sparse model; the image fusion method comprises: using a learned over-complete dictionary to subject source images to joint sparse representation into a common sparse portion and respective private sparse portions; fusing the two types of sparse coefficients obtained through designed fusion rules so as to obtain a fused sparse coefficient; reconstructing an image with the fused sparse coefficient and the dictionary. Simulation experiment results show that the image fusion method provides improved fusion effect for infrared and visible light images.

Description

technical field [0001] The invention belongs to the technical field of image fusion, in particular to an image fusion method based on a joint sparse model. Background technique [0002] With the rapid development of sensor technology, the sensitivity and resolution of sensors and many other performances have been greatly improved. Compared with a single sensor, the data information obtained by multiple sensors is more reliable, complementary and redundant. Therefore, multi-sensor image fusion has become an emerging technology that has attracted much attention in the field of image understanding and computer vision. At present, image fusion technology has been widely used in important fields such as military reconnaissance, remote sensing, social security and medical diagnosis. As a very important part of digital image fusion, the fusion technology of infrared image and visible light image has attracted the attention of scholars at home and abroad, and it is an important re...
