摘要 提出了将一维经验模态分解(1D-EMD)应用到二维图像细节提取的方法.运用1D-EMD方法从水平方向和垂直方向分别处理二维图像,采用最小尺度对齐的原则,可以得到二维图像在水平方向和垂直方向的细节.最后将这2个方向的细节叠加,就可以提取出图像的细节信息.仿真结果证明了该方法的有效性. A new method for extracting image details is presented by using one-dimensional empirical mode decomposition （ 1 -D EMD）. First, a 2-dimensional image is treated with 1 -D EMD method in both vertical and horizontal directions. Then the details of 2-D images in two directions can be achieved by using the principle of alignment of the minimal scale. Finally, overlaying the details in 2 directions will get the information of details of images. Simulation results verified the validity of the method.
