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 | Flags setting drawing features. Possible flags bit values are defined by DrawMatchesFlags. See details above in drawMatches . |

) |
Draws the found matches of keypoints from two images.
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. |
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 | Flags setting drawing features. Possible flags bit values are defined by DrawMatchesFlags. |
This function draws matches of keypoints from two images in the output image. Match is a line connecting two keypoints (circles). See cv::DrawMatchesFlags.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
