| 曲波变换是一种新的多尺度表示方式,其系数包含位置和尺度信息.本文通过对曲波变换系数的分析,提出一种对各层系数区别处理的方式来加强图像边缘信息的方法.实验表明该方法能明显地加强灰暗部分物体的边缘. |
| 英文摘要: |
| 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. |
