| 摘 要： | 提出了一种新的红外图像场景模型,新模型认为红外图像中只包括2种类型的点:目标和起伏噪声。提出了基于这种模型的白化滤波器,给出了对红外图像背景进行白化的算法步骤,并采用基于单个像素局部邻域估计该点功率谱的方法实现了白化滤波器。实验结果表明,这种方法能够很好地白化起伏背景,为进一步的红外目标检测打下了基础。 |

| Abstract: | A new IR background model is presented.It is considered that the new model only includes two kinds of pixels:target pixel and clutter pixel.A whitening filter based on this background model is proposed,and the steps to whiten the background clutter are given.The whitening filter is realized through power spectrum estimation of a single point.Experiment results indicate that this method can whiten the background very well,which makes further IR target detection easier. |
| Keywords: | whitening filter IR (infrared) small target target detection |
