摘要
针对医学图像去噪,利用小波变换具有多分辨率分析和时频两域都具有表征信号局部特征的特点,提出了基于小波包分析的图像消噪算法,并在MATLAB平台上实验仿真,取得了较好的效果。
Aimed at medical image denoising, and utilizing the wavelet transformation which can (accomplish) multi-resolution analysis and can express part-feature of signals on both fields of space and frequency, a method of image denoising based on wavelet packet analysis is proposed. It is shown that better results are obtained when simulation on the MATLAB system are carried out.
