| 摘 要： | 为提取低信噪比红外雷场图象中的目标,采取了一种基于小波分解和能量特征的目标提取方法.根据目标与环境背景在图像小波变换域能量分布特性的不同而对小波分解得到的各变换域通道能量特征值进行计算,并以此为依据提取出目标.实验结果表明,该方法对红外雷场图象有较好的处理效果.

| Abstract: | To extract target feature of infrared image with low SNR, a new scheme based on combination of wavelet decomposition and energy feature is proposed in this paper. According to the energy distribution defference between target and background in wavelet field, the target feature is extracted by calculating the energy feature values of every subchannels obtained from multiscale decomposing. The experimental results demonstrate the vaility of the presented scheme. |
