| 摘 要： | 简要介绍了图像增强方法,分析了海军靶场红外图像的特点,并提出了相应去除噪声和图像增强方法。海军靶场红外图像具有动态范围小、噪声多、对比度低的特点。在图像增强处理时,将多幅背景均匀的红外图像进行统计平均得到背景噪声,通过图像点运算消除背景噪声,用灰度修正的方法完成图像增强处理,取得了较好的图像视觉效果。用该算法对靶场现有低对比度图像进行增强处理取得了较好的结果,验证了算法的有效性。

| Abstract: | The article briefly describes the method of image enhancement,analyzes the characteristics of the NAVY range infrared image,then raises a way to reduce the noise and gray-scale transformation.The infrared image of the NAVY range has the characteristics of low dynamic,high noise and low contrast.First,background noise is calculated by averaging multiple images which have uniform background,and then,image background noise is eliminated by image point operations,finally,the image enhancement is completed with gradation correction.The algorithm achieves better visual effect on other low contrast infrared images of the NAVY range. |
