In this article, we propose a novel single image separation technique by introducing a linear basis equation with full resolution. We evaluate the data independent Fourier basis and learning-based PCA basis to locate the better basis representation of direct and global components. We carefully analyze the importance of high spatial frequency pattern to the effectiveness of our technique. Moreover, we propose the performance enhancement technique to reduce memory usage and computation time for practical implementation.
