红外弱小目标背景抑制中的二维空域廓线法

为了实现天基红外遥感图像中的弱小目标检测，抑制复杂的结构背景，提出了二维空域廓线法。算法以一维时域廓线目标检测理论为基础，将其扩展到二维空域，应用于单帧目标检测。采用二维空域廓线可以获得背景估计，用原始图像减去背景图像可获得包含目标的前景图像。将本文算法与现有的单帧目标检测算法相比，可获得更大的 ROC曲线面积，表明提出算法优于同类算法。

Abstract

To successfully detect dim point targets in space-based infrared remote sensing images while suppressing complex structural backgrounds, a two-dimensional spatial profile method is proposed. The algorithm extends the one-dimensional temporal profile target detection theory to two-dimensional space and applies it to single-frame target detection. The estimated background can be obtained from the two-dimensional spatial profile, after which the foreground image containing the target can be obtained by subtracting the background image from the original image. Compared with the existing single-frame target detection algorithms, the proposed algorithm can obtain a larger ROC curve area, which indicates that two-dimensional spatial profile algorithm outperforms the existing algorithms.
