Detailed Description

Modality that computes quantized gradient orientations from a color image.

Constructor & Destructor Documentation

◆ ColorGradient() [1/2]

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

Default constructor. Uses reasonable default parameter values.

◆ ColorGradient() [2/2]

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

Constructor.

Parameters
weak_thresholdWhen quantizing, discard gradients with magnitude less than this.
num_featuresHow many features a template must contain.
strong_thresholdConsider as candidate features only gradients whose norms are larger than this.
