实现维纳滤波用于语音增强。第一步采用频域谱函数计算最佳的维纳滤波器,再对输入带噪信号进行滤波;第二步是在此基础上的改进,用了自适应的思想,及时根据当前帧的状态更新修正滤波器的系统函数,得到更精确的无噪语音信号。第三步是采用自适应LMS方法,在时域迭代计算滤波器系数,迭代次数足够多时可得到较准确的有用信号。-Implement wiener filtering used in speech enhancement. First step optimum wiener filter is obtai

由于无人机在航拍时会受到相对运动、姿态变化、光学环境、机械振动等因素的影响,导致所拍图像退化。本文使用MATLAB对无人机航拍图像退化过程进行了仿真实验,根据图像退化的原因建立相应的图像退化模型,把清晰的原图像进行退化处理,然后将模拟出来的退化图像分别使用维纳滤波、约束最小二乘(正则)滤波、Lucy-Richardson迭代非线性和盲解卷积4种不同的复原算法进行恢复,达到复原模糊图像的目的。(The application of UAV aerial photography became mor
