| 摘 要： | 小波分析是现代数字信号处理的重要分支。为实现基于小波变换的图像去噪，以小波变换为基础，对一维信号及二维图像信号进行去噪。实验结果表明，基于小波变换的图像处理可以有效地去除噪声，与传统的信号分析技术相比，小波变换能在对信号进行消噪的同时，更好地保留原始信号。

| Abstract: | Wavelet analysis is an lmptoitant branch of modern digital processing.In this paper,we design an image denoising system based on wavelet transform. Firstly, onedimensional signals are enhanced based on wavelet transform, and then, twodimensional image signals are enhanced in the same way. The ex perimental results show that image processing based on wavelet transform can effectively remove the noise, compared with the traditional signal analysis techniques. The wavelet transform eliminates the noise in the sig nal, and preserve the original signal at the same time. |
