| 摘 要： | 为了拓展压缩传感(CS)的应用潜力,提出一种结合双树轮廓波(DT-Contourlet)及CS的多聚焦图像融合方法.该方法首先采用DT-Contourlet对源图像进行分解,提取图像的多尺度信息及方向信息,克服传统轮廓波变换不具平移不变性的缺点.接着,在DT-Contourlet域,将分解系数看成包含稠密和稀疏两部分:...

| Abstract: | In order to expand the capability of Compressed Sensing(CS),a fusion method for multi-focus image using Dual-tree Contourlet(DT-Contourlet) and CS is proposed.First,the source images are decomposed using DT-Contourlet for extracting multiscale and direction information while overcoming the limitation of traditional contourlet which is lack of shift invariance.Then,in DT-Contourlet domain,the decomposition coefficients are treated as containing two components,i.e.,dense and sparse components.The dense compon... |
