基于小波变换图像增强的研究与分析

Study and Analysis of Image Enhancement Based on Wavelet Transform

本文基于小波变换的理论,对图像进行增强分析,并与频域法的低通滤波和高通滤波以及空域法的平滑滤波、锐化滤波进行比较,表明小波变换对改善图像质量较好。

Based on the theory of wavelet transform, we analyze the image enhancement, and compare it with low-pass filtering and high-pass of frequency domain methods and smoothing filtering and sharpening filtering of space domain methods, which indicate that the wavelet transform is able to better improve the quality of images.
