| 摘 要： | 小波阈值滤噪是小波域滤噪的主要方法之一.该文描述了小波图像的滤噪原理和阈值的选取.针对图像滤噪在软、硬阈值的基础上进行了优化,给出了一种修正后的算法并在matlab7.9平台上对图像分别进行硬阈值、软阈值和软硬阈值修正算法滤噪的仿真实验,结果表明软硬阈值修正算法的滤噪效果更优.

| Abstract: | The selection of threshold plays a crucial role in denoising process for an image using wavelet transform.This article describes the denoising principles and the threshold selection of wavelet image.Aiming at the image denoising,the paper proposed a modified algorithm on the basis of the soft and hard threshold,and on matlab7.9 platform respectively made simulation experiment by the methods of soft-threshold,hard-threshold and soft-and-hard-threshold.The result shows the excellent performance of the propose... |
