Positional Arguments

• weak_threshold: float
• num_features: size_t
• strong_threshold: float

Return

• retval: ColorGradient

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

                     larger than this.

Python prototype (for reference only):
