- 背景杂波
Firstly,DTCWT is adopted to decompose the input infrared image,which extracts multi-scale detail features of images. 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。 - 背景混淆
