| 2015-12-01 19:19:54 -0600 | asked a question | What is the sampling method used by cv2.SIFT.detect? Hi, I'm new to OpenCV and SIFT algorithm. I'm using the python version of the library. I know that I can create lots of KeyPoint objects manually and send them to the cv2.SIFT.compute method to get their SIFT descriptors. Although, OpenCV offers another method (cv2.SIFT.detect) to automatically detect a set of KeyPoint objects, given an image. My question is: what is the sampling method adopted by the cv2.SIFT.detect method? Additionally: where in the literature can I find a detailed description of such method? Best regards! |

Hi, 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! |
