- 在数字图像处理中，常常会遇到图像中混杂有许多的噪声。因此，在进行图像处理中，有时要先进行祛除噪声的工作。最常用的祛除噪声的方法是用滤波器进行滤波处理。MATLAB的图像处理工具箱里也设计了许多的滤波器。如均值滤波器、中值滤波器、维纳滤波器等。用户可以很方便的运用一些函数完成数字滤波工作。-In digital image processing, the image often encounter mixed with a lot of noise. Therefore, when the ima

- 本课程设计的主要目的是在MATLAB环境下，使用窗口设计法设计一个滤波器，并对语音信号进行滤波去噪。开发平台为MATLAB7.0，设计方法为窗口设计法。用麦克风采集一段语音信号，绘制波形并观察其频谱，给定相应技术指标，用凯塞窗设计一个满足指标的FIR滤波器，对该语音信号进行滤波去噪处理，比较滤波前后的波形和频谱并进行分析。在滤波前后语音信号波形的变化中，由于我们录制的语音信号噪声不大，所以观察并不明显，但在频域波形中，我们可以明显的看到设计的滤波器对语音信号进行了滤波处理，将噪声进行了滤除。此次
