Abstract:

Due to the fact that the traditional infrared image enhancement methods have imperfect visual effect, we propose an image enhancement method for vehicular infrared night vision images. We establish a waveletgenetic grayscale image enhancement algorithm on the basis of the noncontact thermal image generation principle of the infrared nightvision goggles. Compared with the traditional histogram equalization method and the multiscale Retinex algorithm, the proposed method can improve the image brightness uniformity, avoid excessive enhancement and effectively suppress noise. Experimental results show that the waveletgenetic enhancement algorithm can achieve good performance in enhancing vehicular infrared night vision images.
