摘要: 提出了一种新的基于自适应神经网络模糊推理系统的去除噪声算法。该算法是一个结合了中值滤波、维纳滤波和自适应神经网络模糊推理系统的综合滤波器。噪声点通过算法被准确地估计出来,自适应神经网络模糊推理系统的参数通过训练得到,训练可以通过简单的计算机合成图像来进行。将含噪声的图像、中值滤波后的图像和维纳滤波后的图像作为系统的三个输入,通过一个固定阈值来判断像素点是否为噪声点作为系统的输出,如果判断是噪声点,则通过中值滤波来进行去噪处理,如果判断是非噪声点,则灰度值保持不变。算法的特点就是在能够保持好线条、边缘、细节和纹理的同时,很好地去除噪声点。仿真实验表明,算法可以对噪声污染的图像进行有效的重建,同时不会扭曲图像中的有用信息。
