引入修正因子的局部维纳滤波图像去噪

摘要

The Wiener filter is a classical method in image denoising, and is mean square optimal linear estimator. In this paper an amend factor is introduced to the Wiener filter. The experimental results indicate the revision effectively improves the performance of traditional Wiener filter.%维纳滤波是一种古典的去噪方法,它是最小均方误差意义上的最优线性滤波.在对它的性能分析后,噪声方差修正因子被引入.实验结果表明,这一方法虽然简单,但是有效改善了传统局部维纳滤波的性能.
