基于小波变换的数字监控图像的噪声滤波方法

Noise Filter of Digital Monitor Images Based on Wavelet Transformation

小波分析因具有多分辨率分析能力和时频局部化能力,在处理数字图像时占有很大优势.用小波变换技术的设计一种简单的实用性强的数字监控图像噪声滤波方法,在数字图像处理应用时效果理想.

Due to its capacities of multiresolution and time-frequency location,wavelet analysis has great superiorities in digital image processing.This paper aims at achieving an effect by designing a simple but practical digital monitor images for noise filter on the basis of wavelet transformation.
