提出一种基于非下采样Contourlet变换的红外与可见光图像融合方法.该方法时源图像经非下采样Contourlet变换分解后的高频系数,考虑不同传感器的成像机理进行活性度量,并结合多分辨率系数间相关性来实现加权融合;低频系数则通过一种局部梯度进行活性度量,再采用加权与选择相结合的规则实现融合.最后,通过非下采样Contourlet逆变换重构获得融合图像.实验结果表明了该方法的有效性和可行性.
提齣一種基于非下採樣Contourlet變換的紅外與可見光圖像融閤方法.該方法時源圖像經非下採樣Contourlet變換分解後的高頻繫數,攷慮不同傳感器的成像機理進行活性度量,併結閤多分辨率繫數間相關性來實現加權融閤;低頻繫數則通過一種跼部梯度進行活性度量,再採用加權與選擇相結閤的規則實現融閤.最後,通過非下採樣Contourlet逆變換重構穫得融閤圖像.實驗結果錶明瞭該方法的有效性和可行性.

A fusion method for infrared and visible images based on non-sampled contourlet transform is proposed in this paper. After infrared and visible images decomposed through non-sampled contourlet transform in the proposed method,the high frequency coefficients is fused by means of weight averaging method which is via the combination of activity measure using the different imaging mechanism of sensors and the strategy of the relativity of those multi-resolution coefficients while the low frequency coefficients is fused via the combination of weighting and selection through activity measured by a local gradient. Finally,the fused image is reeonstructed through inverse non-sampled eontoudet transform.The experiment results indicate this fusion method possesses favorable effectivity and feasibility.
