小波分析是近年来发展起来的一种数学方法,在信号与图象处理中有重要的应用.中值滤波是信号处理中常用的一种非线性滤波器,它能够有效地消除瞬时脉冲干扰,并且能够很好地保持信号的边缘信息,在信号和图象处理中得到广泛应用.对中值滤波器与小波变换的结合进行了比较系统的研究.通过实例说明中值滤波器与小波变换相结合具有比单一滤波器更好的效果.
Wavelet analysis is a mathematical method developed in recent years, which has important applications in signal and image processing.Medium-value filtering is a kind of nonlinear filter commonly used in signal processing, which can effectively eliminate the instantaneous pulse interference, And can well maintain the signal edge information, which has been widely used in signal and image processing.Make a comparative study on the combination of median filter and wavelet transform.An example shows that median filter and wavelet transform phase The combination has a better effect than a single filter.
