摘要
对零交叉（ＬＯＧ）算子进行影像的边缘特征检测研究表明，ＬＯＧ算子可以在不同尺度下检测影像的边缘特征，当空间常数σ＜１时，可以产生与边缘一致的零交叉，检测到聚焦良好的物体的精细边缘，并且在一定程度上抑制了反差较小的噪声，从而获得比较满意的应用效果。通常情况下，ｒ＝３σ或４σ即可满足要求。
Research on edge-detecting of an image by zero-crossing opertor (LOG operator) has shown that it can work on multi-scale. Given σ<1, the result consistant with the edge can be obtained, noises with less contrast be restrained to a certain degree and the fine edge with good focus can be detect. In general, when r =3σ or 4σ, this demand can be satisfied.
