同质背景预测用于红外弱小目标检测

背景预测是红外弱小目标检测中抑制背景的主要方法之一.提出了一种同质背景预测算法,在分析空背景下不同背景成分图像灰度特征模型的基础上,首先对图像进行边缘检测,将图像划分为不同灰度性质的区域,然后使用边缘检测结果调制预测权值矩阵.仿真结果表明,该算法对背景杂波具有很好的抑制效果,能够有效保护图像细节,明显降低异质区域像素灰度对预测的不利影响,显著改善低信噪比条件下弱小目标的检测性能.

Detection of Dim Small Target Based on Homogeneous Model of Background Prediction

Background prediction is one of the main method for detection of dim small target. A novel algorithm of background prediction is presented in this paper. Through development of models of the spacial behavior of the static background and cloud edge,the new approach make edge detection first,then the initial image is divided into different area with different grey features. At last,the prediction matrix,modified by the result of the edge detection,is used for background prediction. Experimental results indica...
