Fusion Image Quality Appraisal Method of Dual-spectrum Night Vision Technology

In dual-spectrum night vision technology, the fusion image quality is the key to appraise the fusion method The target of dual-spectrum night vision technology is to enhance the definition of the scenery and the target identification probability, according to the above requirement, using the target identification probability, the signal to noise ratio and the new grayscale accrete matrix three methods to appraise the fusion images. The experimental targets are the fusion image of the low light level (LLL) image and the infrared image, the fusion image of the LLL image and the ultraviolet image, the fusion image of the LLL image and the laser assistant image and the fusion image of the dual-spectrum LLL images. The experimental results indicates the appraisal results of three fusion methods are consistently, specially the gray-scale accrete matrix technique can evaluate quantitatively image definition
