摘要
讨论了红外图像的二维灰度变换增强方法。为了准确地提取和增强景物灰度分布区间,提出了二维直方图的概念,并且通过分区域交增益二维灰度变换来适应各种复杂场景,结果表明,本文方法能够增强原图像的全部信息、明显地改善了视觉观察效果,优于传统的灰度变换方法。
The enhancement of the 2D dynamic range of infrared images for visual observation wasdiscussed. The 2D histogram is proposed to reveal the correct half-tone distribution of targets andsectional 2D gray level transformation is also proposed to adapt varied complex scenes. This method has better effect and more adaptability than the former 1D gray level transformation.Keywoads:Image enhancement Gray level transformation 2D histogram
