摘要
该文介绍了小波阈值去噪的基本原理,描述了图像小波阈值法去噪的过程,并通过仿真实验结果比较了小波阈值去噪方法在选取不同阈值函数下的去噪效果,证明了小波阈值去噪法是一种非常有效的变换域图像去噪方法。
This paper introduces the basic principle of wavelet threshold denoising, and describes the process of image wavelet de-noising threshold value method. Denoising effect is showed by comparing the simulation results of wavelet threshold denoising method in the selection of different threshold function. It is proved that the wavelet threshold denoising method is a very effective method of transform domain image denoising.
