const (

	// The number of points that produce each element of the oriented BRIEF descriptor.
	// The default value 2 means the BRIEF where we take a random point pair and compare their brightnesses, so we get 0/1 response.

func Features ¶

func Features(img gocv.Mat, initial bool) ([]gocv.KeyPoint, gocv.Mat)

Compute the feature vectors for the input image. Learning: https://www.youtube.com/watch?v=4AvTMVD9ig0 for more information (it describes SIFT but works similarly for ORB too) - Detect keypoints in the image - Compute descriptors around each keypoint

func MatchDescriptors ¶

func MatchDescriptors(descA, descB gocv.Mat) []gocv.DMatch
