| 摘 要： | 提出了一种新型的各向异性扩散图像放大的邻域扩散选择平滑法(ADASS),将邻域扩散法与选择平滑滤波器相结合,降低了算法的复杂度,并提高了图像的放大质量.该算法在平滑噪声的同时可以有效地增强边缘,使得放大后的图像无论在边缘处还是平滑区域均能达到理想的效果.实验结果的主观质量及峰值信噪比(PSNR)值表明了算法的有效性.

| Abstract: | Based on the combination of the adjacent diffusion method and the selective smoothing filter,a new anisotropic diffusion algorithm for image enlargement is proposed,which is called as the adjacent diffusion and selective smoothing algorithm(ADASS).Compared with other methods,ADASS is less complex,and moreover,with its characteristic of reducing noise and enhancing edges simultaneously,the higher quality of an enlarged image can be obtained both on edges and in smooth area.The experimental results and PSNR value verify the validity of the proposed algorithm. |
