| 摘 要： | 构造了一套双正交小波滤波器提升方案,并且在图像的不同方向上应用非抽样小波变换来进行边缘检测.为了达到良好的视觉效果,提出了一种对图像进行多方向边缘检测,最后将多方向的检测结果进行逐点融合,得到了较好的效果,证明了算法的可行性.

| Abstract: | In this paper we construct a set of biorthogonal wavelet fiherbanks via lifting scheme and apply the undercimated wavelet transforms along different directions based on differential derivative. In order to achieve good visual quality, a self-adjusted multi-direction fusion approach is proposed. The experimental results show that our method is competitive to classical edge detection methods. |
