2015-03-20 05:33:54 -0600 | commented question | How can I get keypoints for given location in MATLAB Though Its not a standard way. I used the same code as above. detector = cv.FeatureDetector('STAR'); keypoints = detector.detect(im); Then I took first keypoint and changed the location as followed. keypoint1 = keypoints(1); keypoint1.pt = [16,16]; And computed the descriptor for my desired point. extractor = cv.DescriptorExtractor('BRIEF'); descriptors = extractor.compute(im, keypoint1); (In my case, point location is important, size, angle etc of keypoint does not matter) |
2015-03-19 11:50:07 -0600 | commented question | How can I get keypoints for given location in MATLAB I tried, it didn't work. Thank you btw... I resolved the issue by another way (By editing the location of randomly obtained keypoints).. |
2015-03-19 09:13:48 -0600 | commented question | How can I get keypoints for given location in MATLAB @thdrksdfthmn... I have already written a lot of code in MATLAB and used other descriptors such as SURF, BRISK, FREAK etc... and I want to replace BRIEF descriptor only in the code. |
2015-03-19 06:06:29 -0600 | commented question | How can I get keypoints for given location in MATLAB Yes, I know Keypoints carry other information, but I am not able to call cv2.KeyPoint() method in MATLAB... cv.KeyPoint() is not working/available... is there any alternate? |
2015-03-19 05:06:10 -0600 | asked a question | How can I get keypoints for given location in MATLAB I am working in MATLAB, i connected MATLAB with opencv through mexopencv. I want to extract BRIEF descriptors for some keypoints. I am getting keypoints by following code. This code is working fine. But I want dont want to use this command. keypoints = detector.detect(im); Instead, I want to get keypoints on my specific location. For example... I want to do this... keypoint1 = cv.KeyPoint (16,16); But this is not working... How can I get keypoints for my specific location? Thank you, Best Regards, |

2015-03-18 08:25:57 -0600 | commented answer | How to extract BRIEF descriptor for the keypoint on given location. Thank you berak. I am sorry to be too naive. I am working in matlab file. I connected opencv with matlab through mexopencv. I did not import cv either. how can I import cv2 ? should I import it in .m file? |

2015-03-18 07:41:11 -0600 | commented answer | How to extract BRIEF descriptor for the keypoint on given location. Thank you Guanta for your response. Yes, I want to convert points into keypoints. But I am not able to do this. cv.Keypoint() is not working. it seems this function is not avaialable??? I am using opencv in MATLAB that i connected through mexopencv ( By follwing the guidlines given here http://vision.is.tohoku.ac.jp/~kyamag... ) Best Regards, |
2015-03-18 07:02:11 -0600 | asked a question | How to extract BRIEF descriptor for the keypoint on given location. Hello, I recently started working with opencv. I want to extract BRIEF descriptors for some keypoints. For this I am using this code. This code is working fine. But what I actually want is, I want to provide location of keypoints by myself. For Example, I want to extract BRIEF descriptor for the keypoints on location (16,16). Apparently, I can write the code in this way Of course, This is not working. How can I extract BRIEF descriptor for my defined location??? I have already done it with SURF, BRISK and FREAK in matlab. But I want to do it with BRIEF descriptor. Thank you, Best Regards. |
