The dim target usually hides in the constructed background clutter and heavy noise environment. In recent years, researchers pay more and more attention on the detection and tracking of dim target in IR image sequence.
远距离的红外成像目标通常隐藏在高度结构化的背景杂波和强噪声环境中,近些年来,强杂波条件下的可见光和红外小目标的检测研究工作已愈来愈为人们所重视。

Then,according to difference between targets and background clutter signals,the singular value decomposition is introduced to process sub-bands,and maximum eigenvalues are utilized to compose the sub-bands.
首先采用DTCWT对图像进行正变换,获得图像的多尺度和方向细节特征;然后根据目标和背景杂波信号系数在不同尺度之间的差异,对各子带采用奇异值分解进行处理,并利用最大的特征值重构子带;最后将系数调整后的各子带逆变换到图像域,从而将弱小目标和背景杂波分离,达到抑制背景的目的。
