The Discrete Curvelet Transform in Image Enhancement Research
Dan Liu · Journal of Changchun University of Science and Technology · 2012
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.
