Class implementing edge detection algorithm from [46] :
§ computeOrientation()
Python: |
---|
| _dst | = | cv.ximgproc_StructuredEdgeDetection.computeOrientation( | _src[, _dst] | ) |
The function computes orientation from edge image.
- Parameters
-
_src | edge image. |
_dst | orientation image. |
§ detectEdges()
Python: |
---|
| _dst | = | cv.ximgproc_StructuredEdgeDetection.detectEdges( | _src[, _dst] | ) |
The function detects edges in src and draw them to dst.
The algorithm underlies this function is much more robust to texture presence, than common approaches, e.g. Sobel
- Parameters
-
_src | source image (RGB, float, in [0;1]) to detect edges |
_dst | destination image (grayscale, float, in [0;1]) where edges are drawn |
- See also
- Sobel, Canny
§ edgesNms()
Python: |
---|
| _dst | = | cv.ximgproc_StructuredEdgeDetection.edgesNms( | edge_image, orientation_image[, _dst[, r[, s[, m[, isParallel]]]]] | ) |
The function edgenms in edge image and suppress edges where edge is stronger in orthogonal direction.
- Parameters
-
edge_image | edge image from detectEdges function. |
orientation_image | orientation image from computeOrientation function. |
_dst | suppressed image (grayscale, float, in [0;1]) |
r | radius for NMS suppression. |
s | radius for boundary suppression. |
m | multiplier for conservative suppression. |
isParallel | enables/disables parallel computing. |
