AGAST(InputArray, int, bool, DetectorType)

Detects corners using the AGAST algorithm

public static KeyPoint[] AGAST(InputArray image, int threshold, bool nonmaxSuppression, AgastFeatureDetector.DetectorType type)

Parameters

image InputArray

grayscale image where keypoints (corners) are detected.

threshold int

threshold on difference between intensity of the central pixel and pixels of a circle around this pixel.

nonmaxSuppression bool

if true, non-maximum suppression is applied to detected corners (keypoints).

type AgastFeatureDetector.DetectorType

one of the four neighborhoods as defined in the paper

Returns

KeyPoint[]

keypoints detected on the image.
