Wrong Sift points coordinates #20
Comments
@Celebrandil can you please take some of your time to answer, sorry to insist but i gotta use this in my school project which is only a few weeks away |
Do you have an image illustrating the problem? SIFT features are often found in the weirdest of places. |
@Celebrandil this is the code used for drawing
and this is the keypoint detection code:
|
I fail to see what the problem might be. It indeed looks like as if the coordinates are scaled up by a factor of two. |
Hi there, this problem have been fixed? Is this the correct way to extract keypoints? Thank you in advance and have a nice day! P.S. = thank you for your work and sharing! |
Hi, thanks a lot for your great work
I am having an issue with the code
Whenever i try to read the sift points after extracting them from the image, their x and y coordinates aren't where they should be
So i am simply drawing these points over the image with opencv and displaying them in real-time, and the sift points seem to construct shapes of objects in the image but with a larger scale and a big offset
I tried multiplying and dividing the x and y coordinates with the scale attribute of the corresponding sift point but it didn't work
Any idea how this might be solved??
Note: i am running the code on a GT 750m (Kepler w/ cc of 3.0, 4GB DDR3, 12ms to run)
