LoG 算子作为一种零交叉检测器对局部灰度变化敏感 不易受非均匀光场的干扰 可检测
出能较准确反映局部灰度变化的二阶过零点 利用对 LoG 算子检出的零交叉点的插值可求出动
态阈值曲面 并对图像进行二值化 能有效克服非均匀光场对图像分割结果所带来的影响-LoG operator as a zero-crossing detector is sensitive to the local gray are less prone to interference from non-uniform light field can be detected more accurately reflect changes in local gray zero order over the use of the LoG operator zero-crossing detection point interpolation surface can be obtained and dynamic threshold binary image can effectively overcome the non-uniform light field image segmentation results on the impact of
