Abstract

A novel algorithm, which is based on creating the variance image of original image, for infrared image enhancement is proposed. Ordinary spatial filtering is powerful of reducing the noise of image, but it also reduces the contrast of image. Compared with spatial filtering, variance image not only reduces the noise but also enhances the image. In this paper, we combine the variance image and histogram equalization to enhance the infrared image blurred by random noise. The experimental results show the algorithm based on creating variance image is simple and effective, it can be widely used in infrared image enhancement.
