public static void drawKeypoints(Mat image, MatOfKeyPoint keypoints, Mat outImage)
Draws keypoints.
image
- Source image.keypoints
- Keypoints from the source image.outImage
- Output image. Its content depends on the flags
value defining what is drawn in the output image. See possible
flags
bit values below.public static void drawKeypoints(Mat image, MatOfKeyPoint keypoints, Mat outImage, Scalar color, int flags)
Draws keypoints.
image
- Source image.keypoints
- Keypoints from the source image.outImage
- Output image. Its content depends on the flags
value defining what is drawn in the output image. See possible
flags
bit values below.color
- Color of keypoints.flags

. See details above in
"drawMatches".public static void drawMatches(Mat img1, MatOfKeyPoint keypoints1, Mat img2, MatOfKeyPoint keypoints2, MatOfDMatch matches1to2, Mat outImg)
Draws the found matches of keypoints from two images.
This function draws matches of keypoints from two images in the output image.
Match is a line connecting two keypoints (circles). The structure
DrawMatchesFlags
is defined as follows:
img1
- First source image.keypoints1
- Keypoints from the first source image.img2
- Second source image.keypoints2
- Keypoints from the second source image.matches1to2
- Matches from the first image to the second one, which
means that keypoints1[i]
has a corresponding point in
keypoints2[matches[i]]
.outImg
- Output image. Its content depends on the flags
value defining what is drawn in the output image. See possible
flags
bit values below.public static void drawMatches(Mat img1, MatOfKeyPoint keypoints1, Mat img2, MatOfKeyPoint keypoints2, MatOfDMatch matches1to2, Mat outImg, Scalar matchColor, Scalar singlePointColor, MatOfByte matchesMask, int flags)

keypoints2[matches[i]]
.outImg
- Output image. Its content depends on the flags
value defining what is drawn in the output image. See possible
flags
bit values below.matchColor
- Color of matches (lines and connected keypoints). If
matchColor==Scalar.all(-1)
, the color is generated randomly.singlePointColor
- Color of single keypoints (circles), which means that
keypoints do not have the matches. If singlePointColor==Scalar.all(-1)
,
the color is generated randomly.matchesMask
- Mask determining which matches are drawn. If the mask is
empty, all matches are drawn.flags
