Canny Edge Detection

This process is the Digital image processing in OpenCV libary to find an edge image by using Canny algorithm.

using function.

void cvCanny( const CvArr* image, CvArr* edges, double threshold1,
double threshold2, int aperture_size=3 );

Example for use OpenCV libary.

IplImage *pCanny=cvCreateImage(cvGetSize(pimage),IPL_DEPTH_8U,1);
cvCanny (pGray,pCanny, 200,250, 3 );
cvNamedWindow("Canny",CV_WINDOW_AUTOSIZE);
cvShowImage("Canny", pCanny);

result.
