| 摘 要： | 根据数字图像中椒盐噪声像素的特点，提出了一种非常有效的椒盐噪声检测算法：两极门限检测法，并通过实验验证了该算法的有效性。在两极门限检测法基础上，本文进一步提出了一种改进的中值滤波算法，该算法能够有效地滤除数字图像中的高密度椒盐噪声，同时尽可能地保留图像细节。

| Abstract: | This paper proposes a very effective salt and pepper noise detecting algorithm,two poles threshold detecting method,according to the feature of salt and pepper noise pixels in digital images,and validates this algorithm's validity by experiment.Based on the two poles threshold detecting method,this paper proposes an improved median filtering algorithm farther.The improved algorithm can filter highly density salt and pepper noises in digital images effectively,and preserve image details by the greatest exten... |
