AnchorThresholdValue

int cv::ximgproc::EdgeDrawing::Params::AnchorThresholdValue

threshold value used to select anchor points. Default value is 0

Examples:

fld_lines.cpp.

EdgeDetectionOperator

int cv::ximgproc::EdgeDrawing::Params::EdgeDetectionOperator

indicates the operator used for gradient calculation.

one of the flags cv::ximgproc::EdgeDrawing::GradientOperator. Default value is PREWITT

Examples:

fld_lines.cpp.

GradientThresholdValue

int cv::ximgproc::EdgeDrawing::Params::GradientThresholdValue

threshold value of gradiential difference between pixels. Used to create gradient image. Default value is 20

Examples:

fld_lines.cpp.

LineFitErrorThreshold

double cv::ximgproc::EdgeDrawing::Params::LineFitErrorThreshold

Default value is 1.0.
