	/// Class containing the methods needed for Quasi Dense Stereo computation.
	///
	/// This module contains the code to perform quasi dense stereo matching.
	/// The method initially starts with a sparse 3D reconstruction based on feature matching across a
	/// stereo image pair and subsequently propagates the structure into neighboring image regions.
	/// To obtain initial seed correspondences, the algorithm locates Shi and Tomashi features in the
	/// left image of the stereo pair and then tracks them using pyramidal Lucas-Kanade in the right image.
	/// To densify the sparse correspondences, the algorithm computes the zero-mean normalized
	/// cross-correlation (ZNCC) in small patches around every seed pair and uses it as a quality metric
	/// for each match. In this code, we introduce a custom structure to store the location and ZNCC value
	/// of correspondences called "Match". Seed Matches are stored in a priority queue sorted according to
	/// their ZNCC value, allowing for the best quality Match to be readily available. The algorithm pops
	/// Matches and uses them to extract new matches around them. This is done by considering a small
	/// neighboring area around each Seed and retrieving correspondences above a certain texture threshold
	/// that are not previously computed. New matches are stored in the seed priority queue and used as seeds.
	/// The propagation process ends when no additional matches can be retrieved.
	/// ## See also
