opencv Edge detection
Syntax
- edges = cv2.Canny(image, threshold1, threshold2[, edges[, apertureSize[, L2gradient]]])
- void Canny(InputArray image, OutputArray edges, double threshold1, double threshold2, int apertureSize=3, bool L2gradient=false
Parameters
| Parameter | Details |
|---|---|
| image | Input image |
| edges | Output image |
| threshold1 | First threshold for hysteresis procedure |
| threshold2 | Second threshold for hysteresis procedure |
| apertureSize | Aperture size for Sobel operator |
| L2gradient | Flag indicating whether a more accurate algorithm for image gradient should be used |
