Class implementing edge detection algorithm from Dollar2013 :

Required methods

fn as_raw_StructuredEdgeDetection(&self) -> *const c_void

Provided methods

fn detect_edges(
    &self,
    _src: &dyn ToInputArray,
    _dst: &mut dyn ToOutputArray
) -> Result<()>

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

fn compute_orientation(
    &self,
    _src: &dyn ToInputArray,
    _dst: &mut dyn ToOutputArray
) -> Result<()>

The function computes orientation from edge image.

Parameters

• _src: edge image.
• _dst: orientation image.

fn edges_nms(
    &self,
    edge_image: &dyn ToInputArray,
    orientation_image: &dyn ToInputArray,
    _dst: &mut dyn ToOutputArray,
    r: i32,
    s: i32,
    m: f32,
    is_parallel: bool
) -> Result<()>

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.

C++ default parameters

• r: 2
• s: 0
• m: 1
• is_parallel: true
