离散Curvelet变换在图像增强中的应用研究

The Discrete Curvelet Transform in Image Enhancement Research

近几年来,图像增强技术随着计算机软件和硬件技术的发展而越来越有广阔的应用空间。图像增强技术包括传统图像增强技术和以传统技术为基础的新的图像增强技术。其中,Curvelet变换是基于脊背理论发展的一种新的图像增强技术。本文是在离散Curvelet变换算法的基础上做了部分修改和尝试,并且对Curvelet变换系数进行系数修正,通过MAT-LAB实现该改进的图像增强算法。

In recent years,image enhancement technique has be more wide application space along with the computer software and hardware technology development.Image enhancement techniques include traditional image enhancement technique and the new image enhancement technique based on the traditional technology.Among them,Curvelet transform,which is based on the ridge of the development of the theory of wave,is a kind of new way about the image enhancement technology,Some revisons and attempts were made on the basis of discrete Curvelet transform algorithm,and the coefficient of curevelet fransform was revised also.The improved image enhancement was practised by MATLAB.
