void cvCanny( const CvArr* image, CvArr* edges, double threshold1,
double threshold2, int aperture_size=3 );
- image
- Input image.
- edges
- Image to store the edges found by the function.
- threshold1
- The first threshold.
- threshold2
- The second threshold.
- aperture_size
- Aperture parameter for Sobel operator (see cvSobel).
中的 threshold1 和 threshold2 的范围是多少, 是[0 1] 还是[0 255]; 还有一个问题就是, 有没有什么方法可以自动设定这两个参数的, 谢谢.--
