| Abstract: | The curvelet transform is a new family of multi-scale representation containing the information about the scale and location parameters.According to the analysis about the coefficient of curvelet transform,a novel method is proposed in this paper.The method uses different means to deal with different scale of the coefficient to enhance the edge of image.The experimental results show that the method can observably enhance the edge in the gloom area of the image. |
