    摘要:

    針對紅外光和可見光傳感器難以同時獲取清晰的目標(biāo)和場景問題,,提出一種基于非下采樣Contourlet系數(shù)壓縮感知的可見光和紅外圖像融合方法,。首先采用非下采樣Contourlet變換對可見光圖像和紅外圖像分別進行多尺度,、多方向分解,,得到各自的非下采樣Contourlet系數(shù),;然后對兩種圖像的低頻系數(shù)采用加權(quán)與平均相結(jié)合的系數(shù)融合方案直接融合,對兩種圖像的帶通方向子帶系數(shù)采用偽隨機傅里葉矩陣進行觀測后將觀測值進行加權(quán)融合,,再對融合后的帶通方向子帶觀測值進行系數(shù)重構(gòu),,最后通過非下采樣Contourlet逆變換重構(gòu)圖像。數(shù)值實驗顯示,,該融合算法計算復(fù)雜度低,,融合效果好,能同時得到目標(biāo)和場景均清晰的融合圖像,。

    Abstract:

    In order to solve the problem that the infrared light sensor and the visible light sensor can’t get clear images simultaneously, a nonsubsampled Contourlet coefficient compressive sensing based on infrared and visible image fusion method was proposed. Firstly, the nonsubsampled Contourlet transformation method was used to do multiscale multi directional image decomposition for the infrared and visible image. Each nonsubsampled Contourlet coefficient of them was got. Then, the low-frequency coefficients of the infrared and visible image were fused by the weighted average fusion method. The band pass sub band coefficients by the pseudo random Fourier matrix observations weights fusion method were used. After that, fused band pass sub band coefficients were reconstructed. Finally, image by the inverse nonsubsampled Contourlet transformation were reconstructed. The experiment results showed that this fusion algorithm can get image with clear object and background, and it has the low computational complexity and good fusion effect. 
