Detailed Description

Modality that computes quantized gradient orientations from a color image.

Constructor & Destructor Documentation

cv::linemod::ColorGradient::ColorGradient ( )

Default constructor. Uses reasonable default parameter values.

cv::linemod::ColorGradient::ColorGradient	(	float	weak_threshold,
		size_t	num_features,
		float	strong_threshold
	)

Constructor.

Parameters

weak_threshold	When quantizing, discard gradients with magnitude less than this.
num_features	How many features a template must contain.
strong_threshold	Consider as candidate features only gradients whose norms are larger than this.
