当我使用Canny边缘算法,它产生预期的颜色浓线对面的2个边,但我想只显示一个边缘,从而使我的直线和曲线检测算法我如何能更复杂,任何想法做到这一点?
下面是代码:
bool CannyEdgeDetection(DataStructure& col)
{
Mat src, src_gray;
Mat dst, detected_edges, fin;
int WhiteCount = 0, BCount = 0;
char szFil1[32] = "ocv.bmp";
char szFil2[32] = "dst.bmp";
src = imread(szFil1);
dst = imread(szFil1);
blur( src_gray, detected_edges, Size(3,3) );
Canny( src, dst, 100, 200, 3 );
imwrite(szFil2, dst );
IplImage* img = cvLoadImage(szFil2);
int height = img->height;
int width = img->width;
int step = img->widthStep;
int channels = img->nChannels;
uchar * datau = (uchar *)img->imageData;
for(int i=0;i<height;i++){
for(int j=0;j<width;j++){
for(int k=0;k<channels;k++){
datau[i*step+j*channels+k] = 255 - datau[i*step+j*channels+k];
if (datau[i*step+j*channels+k]==0){
WhiteCount++;
col.pixel_col [i][j] = 2;
}
else{BCount++;
col.pixel_col[i][j] = 0;
}
}
}
}
cvSaveImage("img.bmp" ,img);
return 0;
}
这是不是原来的图像,但类似:
哪一部分做我注释掉能在白色背景阅读黑色图像? 或任何颜色的图像?
bool done;
do
{
cv::morphologyEx(img, temp, cv::MORPH_OPEN, element);
cv::bitwise_not(temp, temp);
cv::bitwise_and(img, temp, temp);
cv::bitwise_or(skel, temp, skel);
cv::erode(img, img, element);
double max;
cv::minMaxLoc(img, 0, &max);
done = (max == 0);
} while (!done);
