"OpenCV, C + +" implements down-grating tracking to detect edges

The design functions are as follows:

which

void int int low);

In the parameter list, the first entry is the grayscale image to be traced, and the second is the output image.

The third high is the detection threshold, and the fourth low is the tracking threshold value.

voidGratingdetect (Mat &graysrc, Mat &graydst,intHighintLow ) {    intRowNum =graysrc.rows; intColnum =Graysrc.cols;  for(inti =0; i < RowNum; i++) {Uchar* D_data = graydst.ptr<uchar>(i); Uchar* S_data = graysrc.ptr<uchar>(i);  for(intj =0; J < Colnum; J + +)        {            if(S_data[j] >=High ) {D_data[j]=255; inttemp =S_data[j]; if(I < rowNum-1) {D_data= graydst.ptr<uchar> (i +1); S_data= graysrc.ptr<uchar> (i +1); if(J >0&& J < Colnum-1)                    {                         for(intK =-1; K <2; k++)                        {                            if(ABS (Temp-s_data[j + K]) <=Low ) D_data[j+ K] =255; Elsed_data[j+ K] =0; }} d_data= graydst.ptr<uchar>(i); S_data= graysrc.ptr<uchar>(i); }            }            ElseD_data[j]=0; }    }}
