Implementation of Contourlet Transform with Enhanced Laplacian Pyramid Decomposition
During Laplacian pyramid decomposition in contourlet transform, the resulting bandpass images exhibit oscillations near singularity points, which degrades image denoising performance. To address this issue, we propose an improved Laplacian pyramid decomposition that eliminates edge oscillations. This enhanced method implements contourlet transform using the modified pyramid structure and incorporates adaptive denoising techniques. Experimental results demonstrate significant improvement in peak signal-to-noise ratio (PSNR) compared to conventional contourlet transform adaptive denoising algorithms, along with substantial visual quality enhancement.
