Remote Sensing Image Interpolation via the Nonsubsampled Contourlet Transform

摘要：

A novel nonsubsampled contourlet Bi-linear interpolation algorithm for remote sensing image is proposed, which is based on the estimation of detail nonsubsampled contourlet coefficients at high resolution scales. The method employs Bi-linear interpolation algorithm to anticipate the high frequency component on high resolution from the high frequency component on low resolution. The experiment results demonstrate that the algorithm can get a higher PSNR and keep more image detail information than traditional interpolation algorithms.
