Pixel-level visible image and infrared image fusion based on wavelet transform

Abstract

Vision sensor is one of the sensors that can obtain the most abundant environmental information by a single sensor at present, but a single sensor is still limited by the influence of complex environment, which makes the obtained environmental information and actual environmental information quite different. Therefore, the fusion of infrared vision sensor and visible light vision sensor is used to express the environment in multiple dimensions after fusion, which can effectively enrich the image information and supplement the required environmental information. In this paper, two-dimensional discrete wavelet is used to process the visible image and infrared image separately. The obtained fusion image retains the information of the original image and solves the problem of artifacts and ghosting of the fusion image.
