detectEdges
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 edgesdst
- destination image (grayscale, float, in [0;1]) where edges are drawn SEE: Sobel, Canny
-
computeOrientation
The function computes orientation from edge image.- Parameters:
src
- edge image.dst
- orientation image.
-
edgesNms
public void edgesNms(Mat edge_image, Mat orientation_image, Mat dst, int r, int s, float m, boolean 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.
-
edgesNms
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.
-
edgesNms
