摘要
对噪声图像进行不同方向的滤波，根据方向滤波的信息，定义了方向信息测度作为判定噪声点与边缘点的度量．使用了二次Ｂ样条小波进行边缘检测，根据方向信息测度调整边缘检测中的滤波尺度，实现了多尺度边缘检测的自适应尺度调整．最后给出了实验比较结果。
In this paper, a new edge detection method is presented. In order to distinguish noise and edge, the noise image is filtered in four different directions. Direction information measure is defined on the basis of these different direction filter results. The cubic B spine wavelet whose scale is adjusted by direction information measure is used to detect edge. Finally, experiment results and comparisons are given. This method is proved to be effective to these images that have obvious direction characteristics.
