针对红外与可见光图像特点，提出一种基于非下采样Contourlet变换（NSCT）的红外与可见光图像融合算法。该算法对源图像进行NSCT分解，得到低频分量和各带通方向子带分量；引入图像区域相关系数决策度，对低频分量和带通方向子带分量采用不同的融合规则进行融合；最后经过NSCT逆变换得到融合图像。实验证明，该方法可以更好地保留目标信息和图像细节信息。
針對紅外與可見光圖像特點，提齣一種基于非下採樣Contourlet變換（NSCT）的紅外與可見光圖像融閤算法。該算法對源圖像進行NSCT分解，得到低頻分量和各帶通方嚮子帶分量；引入圖像區域相關繫數決策度，對低頻分量和帶通方嚮子帶分量採用不同的融閤規則進行融閤；最後經過NSCT逆變換得到融閤圖像。實驗證明，該方法可以更好地保留目標信息和圖像細節信息。

Aiming at the features of infrared and visible images,a fusion algorithm based on Nonsubsampled Contourlet Transform ( NSCT ) was proposed for fusion of infrared and visible images .Firstly,the original images were decomposed by using NSCT,then the low frequency coefficients and high frequency coefficients were obtained .The correlation coefficient decision of the image area was introduced,and different fusion rules were used for fusion of low frequency components and bandpass sub -band components .The final fused image was obtained after NSCT inverse transformation .The experiments proves that this method can better keep the target information and image details .
