Suppress edges (nonmaximum suppression)

dst = obj.edgesNms(edge_image, orientation_image)
dst = obj.edgesNms(..., 'OptionName',optionValue, ...)

Input

• edge_image edge image from detectEdges function.
• orientation_image orientation image from computeOrientation function.

Output

• dst suppressed image (grayscale, float, in [0;1]).

Options

• R radius for NMS suppression. default 2
• S radius for boundary suppression. default 0
• M multiplier for conservative suppression. default 1.0
• IsParallel enables/disables parallel computing. default true

The function suppresses edges where edge is stronger in orthogonal direction.
