What is the meaning of a keypoint color ploted by cv2.drawKeypoints? [closed]

asked 2015-05-04 00:35:40 -0500


I'm using SIFT/SURF algorithms and the function cv2.drawKeypoints() to plot keypoints over the image. My question is: is there any meaning in the colors of the keypoints?

Here goes one example: http://opencv-python-tutroals.readthe...

Thanks in advance!
