| 摘 要： | 提出一种基于非下采样Contourlet变换（NSCT）的多传感器图像边缘检测方法,通过非下采样金字塔（NSP）和非下采样方向滤波器组（NSDFB）实现了对图像的多尺度多方向分解。在检测处理中,采用改进的一致性校验策略：高频系数除了进行本层的一致性校验外,还进行多层之间的一致性校验。非下采样Contourlet变换保留了Contourlet变换良好的多分辨率特性,又具有平移不变性,更适应于进行多传感图像融合,为图像边缘检测提供了新的方法。

| Abstract: | A kind of multi-sensor image edge detection method based on nonsubsampled contourlet transform(NSCT) is introduced.The decomposition of the source images in a multi-scale and multi-direction way is realized by nonsubsampled pyramid(NSP) and nonsubsampled directional filter banks(NSDFB).The improved consistency checking strategy was used in the detection process: high frequency coefficients were processed using consistency checking not only in their own level but also in all high frequency levels.The nonsubs... |
