多种噪声图象的自适应韧性滤波

Adaptive Robust Filtering of Image with Different Kinds of Noise

本文提出了一种用于噪声图象的自适应韧性滤波器。它不需要先验的图象统计分布知识,具有良好的滤波韧性。它能同时滤除图象中的独立加性噪声、信号有关噪声和脉冲噪声。这种滤波器有很好的边缘信号保护作用并易于实现。

In this paper, an adaptive robust filter for noisy images is proposed. It possesses quite good filtering robustness and does not require a priori statistic distribution knowledge of the image. It removes a combination of signal-independent additive noise, signal-dependent noise and impulsive noise simulteneously. The filter also preserve the signal edges very well and is simple to implement.
