图像增强技术是数字图像处理的的一个重要分支,提出了一种小波软阈值的图像增强算法,首先对原图像进行小波分解,得到分解后的小波系数,对给定的阈值,应用局部小波软阈值方法对小波系数处理,再将处理后的图像进行小波逆变换,得到增强后的图像.该方法在增强图像的同时,有效地抑制图像的噪声,较好地保持图像的边缘结构.

Image enhancement is an important part of digital image processing.This paper proposes a novel algorithm for image enhancement through soft-threshold.The first step is to part the input image into wavelet coefficients using wavelet transform decomposition,applying soft-threshold to process the coefficients.Then wavelet inverse transform is used to restore the output image to obtain the enhanced image.The method can denoise the image and preserve edge information while enhancing the original image.
