| 摘要: |
| 提出一种基于小波包分解的多尺度图象边缘检测算法,对经小波包分解所得到的高频部分加以考虑,避免了普通的利用小波分解进行边缘检测时忽略图象高频部分的缺陷.在此基础上,通过对实际图象运用此算法,对其检测效果同其他方法进行分析与比较,结果证明此方法在复杂图象边缘检测中具有较好的效果. |

| Abstract: |
| A new approach for
multiscale image edge detection based on the wavelet package decomposition is proposed.
Generally, the wavelet transform way is used to detect the edge of the image,but the high
part of the frequency is not considered and analyzed. I |
