| 摘 要： | 以图像小波域分形编码为基础,研究了一种新的图像去噪方案.该方案在图像的小波域上,通过预测校正算法,利用含噪图像的小波系数对无噪图像的FW码进行估计,并通过FW解码和小波逆变换获得去噪图像.实验证明,该方案具有较好的去噪效果,并可以有效地保护细节.

| Abstract: | Based on the Fractal-Wavelet coding,this article studies one kind of new image denoising scheme.This scheme first takes advantage of the image wavelet transformation,and then predicts the FW codes of the noise-free image from the wavelet coefficient of the noised version,and finally obtains the noise-free image by decoding the predicted FW code.It is proved by the experiment that this scheme has strong ability of image denoising,and it can protect the details of the image effectively when denoising is pract... |
