Paper Abstract

The area of low light level (LLL) night vision, improving the LLL image quality by using infrared laser assistant vision technology has been proposed as an important subject. In this paper, we realized the fusion of the instantaneous laser assistant vision image and LLL image in frequency-domain. The features of the two kinds of images are different because the spectrums they respond are different. In frequency-domain, we assign different threshold of the high and the low frequency in order to realize the fusion processing. The details and the contours of the scene are enhanced respectively. The experiment results show that the fusion of instantaneous laser assistant vision infrared image and LLL image can improve the image quality effectively. The fused images and the source images are presented in this paper.
