void cv::Sobel( InputArray _src, OutputArray _dst, int ddepth, int dx, int dy, int ksize, double scale, double delta, int borderType )

src 输入图像
dst 输出图像 the same size and the same number of channels as src .
ddepth 输出图像深度,输入图像为CV_8U,sobel的结果一般为CV_16S
dx order of the derivative x.:x导数的阶数???(只能0、1、2)
dy order of the derivative y.:y导数的阶数???
ksize size of the extended Sobel kernel; it must be 1, 3, 5, or 7. :差分算子的核大小
scale optional scale factor for the computed derivative values; by default, no scaling is applied :导数结果的比例系数
delta optional delta value that is added to the results prior to storing them in dst.:偏移值
borderType pixel extrapolation method, see cv::BorderTypes

说明:

1、Sobel方法:离散性差分算子
